A Primer on Scientific Programming with Python (Texts in Computational Science and Engineering) ReviewDon't be fooled by the title or the first chapter, this book provides
a solid introduction for using Python in scientific applications. The
main application areas covered are calculating the value of functions,
both built in and user supplied, plotting data, finding the roots of
equations, difference equations, numerical differentiation, numerical
integration and the solution to differential equations by numerical
methods.
Along the way you will learn how to use lists, tuples, dictionaries,
loops, list comprehension, lambda functions, Numpy arrays, file I/O
and Python Classes for programming scientific applications. Two
main highlights of the book are the thorough explanations the author
provides on how to use most of the features of Python and the copious
number of examples with answers. Other features are an example on how
to extract data from a Web Page and scitools. Scitools provides a
Matlab type of interface to gnuplot. About the only thing missing is
a summary on how to install Numpy, Scipy, Scitools, gunplot, and
gnuplot.py.A Primer on Scientific Programming with Python (Texts in Computational Science and Engineering) Overview
The book serves as a first introduction to computer programming of scientific applications, using the high-level Python language. The exposition is example- and problem-oriented, where the applications are taken from mathematics, numerical calculus, statistics, physics, biology, and finance. The book teaches "Matlab-style" and procedural programming as well as object-oriented programming. High school mathematics is a required background, and it is advantageous to study classical and numerical one-variable calculus in parallel with reading this book. Besides learning how to program computers, the reader will also learn how to solve mathematical problems, arising in various branches of science and engineering, with the aid of numerical methods and programming. By blending programming, mathematics and scientific applications, the book lays a solid foundation for practicing computational science.

Libre Ebook Reader Pro (white) ReviewI've had the Libre for a few weeks now and I've been very impressed with it. I chose it over the Kindle and Nook for a number of reasons: available formats, lower cost, and the fact that I don't need the instant purchase capability. The Libre comes with a 2GB SD card with 100 classic books loaded in the .txt format. 100 books takes up almost no space on that card - there is room left for hundreds and hundreds of others. Loading the books onto the Libre is simply a matter of connecting it to your computer and dragging-and-dropping the books into the pre-set folder or into folders you set up. There are plenty of sources out there for ebooks that you can load up your reader with whatever genre assortment you like, so the immediate gratification of instant purchases is unnecessary, IMO.
I chose the white color over the black, and I am happy with my choice. Frankly, I'm sick of black-colored electronic gadgets - I have way too many of them already. I find the white frame doesn't intrude on my focus. The "e-paper" of this reader had a slightly gray-greenish tinge to it, from the LCD design, as opposed to the whiter backgrounds of the e-ink type readers, but I've found the difference to be negligible. The letters are crisp on the background, and I've had no difficulty in reading it in sunlight, twilight, and incandescent light. I haven't had any problem with eyestrain, and I find it much easier to read than reading on a computer back-lit screen. I like the fact that the page-changing is seamless, without the flashing of the e-ink type readers.
The controls are easy to use. There's a up-down slide switch on the left side, left-right buttons on the left front, and left-right buttons on the right front that allow you to turn the pages. There are also alpha-numeric tabs on the right side that allows quick choices, but the same can be done using the directional buttons on the lower right front. So there are a number of different ways to accomplish the same task if you are right-or-left handed, or if you have some physical infirmity. I have had no problem adjusting font sizes from very small to very large, and there's an auto-page-turn function for fast readers or people with a disability.
I would say that the weight of the reader is probably comparable to that of a 500-600 page paperback book, without the book's bulk. I've found that strange at first, but now I'm used to it. One thing that I think is probably true for all ebook readers is that the user has to get used to a different way of holding a "book" to read, because you're not opening a book wide and you're flipping pages without having to lift your hand.
It should be noted that most of the ebook readers out there today - even if they say they handle .pdf formats - have problems with that format due to its basic nature and the smaller size of the eReader screens. Reading a .pdf exactly as formated usually results in tiny text. Expanding the font size sometimes has some odd results. The Libre allows you to change the view from portrait to landscape mode for better viewing, and it also has the reflow feature to allow .pdf formatting to resize itself for the smaller screen.
I haven't noticed any difficulty with the battery life. There are auto-off settings that allow the eReader to turn itself off after set periods of inactivity. I've had no problem reading complete books on a single charge.
Another thing I like about the Libre is that it comes with a USB cord to connect to the computer for file transfers and/or charging, an AC adapter for charging, earbuds, a 2GB SD card, and a protective case. So there's no extra accessories that you have to spend extra money on.
I've found that I prefer to use the .epub format for my books, though individual tastes might vary. The good thing about the Libre is that it gives you a nice number of formats to choose from. And if you happen to find an ebook that's in a format that the Libre doesn't natively handle, it's very easy to convert almost any ebook format to one you prefer by using the freeware program Calibre (an extremely useful and well-designed program).
To date, I haven't tested out the MP3 player functions of the Libre, or its feature that allows you to play background music while reading. Since it does handle the MP3 format, I would think that it is possible to download audiobooks to it. And with the capacity to use even larger SD cards, to store a number of them on the device. So in addition to having the ability to read books, you should also be able to listen to them; and using the headphone output plug, should be able to connect it to the MP3 input in your car (if you have one) making this a really handy device for traveling. I'll have to try this out. =)
Note also that the Aluratek Libre and the Etaco JetBook are physically the same eBook reader but sold by different companies. They differ in their firmware and the formats handled. Right now the Libre has the format edge because it'll handle both DRM and non-DRM .pdf. The Jetbook seems to have the edge if you want to use it with ebooks in other languages.
For those of you trying to make up you mind about which eBook reader is right for you, I would suggest checking out the forums at [...]. They aren't affilitated with any specific product; it is a great resource and they have a number of informative Wikis comparing reader specifications, ebook formats, and listing both free and paid ebook sources.

Kindle DX Wireless Reading Device, Free 3G, 9.7" Display, White, 3G Works Globally – 2nd Generation ReviewI have owned both Kindle 1 and Kindle 2, so I'm already committed to the basic idea: e-ink reading in a slim form factor with excellent connectivity to a large selection of books and subscriptions. I have come to rely on my Kindle experience, and it has seriously enhanced my reading.
The DX was not an obvious upgrade for me, but two features put me over the edge: the larger screen, and the native PDF reader. I now have the DX in my hands, and can report PROS, CONS, and NEUTRALS:
PROS:
-- the larger screen is a definite plus. I use the larger type size on my Kindle 2 (older eyes), and at this type size I get far more text per page on the DX. This makes the whole reading experience more book-like (and should be a boon to people who buy large-print books.)
-- the screen is also sharper and crisper than my Kindle 2 in a side-by-side comparison: the text is darker, and the contrast is much better, making for better visibility overall.
-- on a side note, the larger screen also makes it possible to read poetry on the kindle, even at large type sizes. On earlier Kindles, the smaller screen cut off lines, so that you would lose the sense of when the poet ended the line. On the DX, you can see the whole line exactly as the poet meant it, with the cut-off in the right spot.
-- the PDF reader works as advertised, and is extremely convenient. PDF documents appear on the DX exactly as they do on a computer screen. Moreover, you can drag and drop your documents directly to the device using the USB cable (or use the for-a-fee email if you absolutely must.) The only downside: at least for the documents that I've used so far, I cannot adjust the type size as I can with native Kindle documents.
-- screen rotation also works as advertised: it operates as a mild zoom on both graphics and text and offsets slightly the downside of not being able to adjust the typesize on PDF documents. One nice design touch: the four-way navigation stick introduced on the Kindle 2 is rotation-sensitive, and will move as expected relative to the screen rotation.
-- more of the device space is devoted to the screen, while the white plastic border around the screen seems to have shrunk, both in general and compared to the proportion of screen to plastic on the Kindle 2. I like this (but see below about the keyboard).
-- storage: I like the increase in storage space, and don't mind the lack of an external storage card. I can see some people having trouble with this, but only those folks who either a) must regularly carry around PDF documents totalling more than 3.5 GB of space or b) must have nearly 3500 books regularly at their fingertips. I fall in neither category.
CONS:
-- price: it's expensive, as you can tell pretty quickly. If you value the larger size, and the native PDF reader, these features may justify the roughly 30% premium you pay for the DX over the Kindle 2. In truth, the DX SHOULD cost more than the Kindle 2, and a 30% premium isn't unreasonable. But, for my money, Amazon should drop the price on the Kindle 2 to $300 or so, and charge $400 or a little less for the DX. Still, I bought it, and will keep it at this price.
-- one-sided navigation buttons: all of the buttons are now on the right side, and none are on the left. I'm a righty, so I shouldn't complain, but I found myself using both sides on the Kindle 2. Lefties have reason to complain, I think.
-- One-handed handling: I often read while I walk, with my Kindle in one hand, and something else in my other. Because of the button layout, this will be more difficult on the DX.
-- metal backing: I miss the tacky rubberized backing on my Kindle 1. When I placed my Kindle 1 on an inclined surface, it stayed in place. Not so my Kindle 2 and now my DX. This is not a complaint specific to the DX, but it's still there.
NEUTRALS (i.e. things worth noting):
-- weight: the DX is heavier, noticeably so. This is only an issue if, like me, you regularly use the kindle with one hand . . . and even so, it's still doable.
-- keyboard: the keyboard has 4 rows, and not 5: the top row of numbers from the Kindle 1 and 2 has been merged into the top qwerty row, so that numbers are now only accessible with an alt-key combination. The keys are vertically thinner too, so that the whole keyboard is no more than 1" tall (compared to over an 1.5" on the Kindle 2). At the same time, the keys themselves are a bit easier to press, a bit more protruding than on the Kindle 2. For someone with big fingers (like me), this will be a slightly harder keyboard to use, but only slightly.
That's all I can see. Overall, the pluses outweigh the minuses for me, and I'm satisfied with my purchase. I can now think of using my DX for work documents on a regular basis, because of the PDF reader. The screen size and screen rotation make the overall reading experience more immersive.
Overall, the DX feels more like text and less like device and comes closer to the stated goal of the Kindle: for the device to disappear, leaving only the joy of reading.Kindle DX Wireless Reading Device, Free 3G, 9.7" Display, White, 3G Works Globally – 2nd Generation Overview

Kindle Wireless Reading Device (6" Display, U.S. Wireless) ReviewI'm a new Kindle 2 owner and I did not own a Kindle 1. I was very interested in the original Kindle, but had decided to wait for improvements based on customer feedback after it was released, especially the accidental page turning issue. Since it looked like they made the improvements I was waiting for (one of the others was a bit more free space on the case to hold it) I took the plunge and got the new one.
I thought I'd start with listing my reasons for getting the Kindle, since I think that can sometimes help others who are sitting on the fence to decide if it's for them or not.
* Storage. I'm out of shelf space and all the boxes of books do little to add to the ambience of my one bedroom apartment. On the rare occasions I want to read something again trying to find the book in all the boxes is an exercise in frustration.
* eInk technology. I love books and using an electronic gadget isn't the same experience. The new technology has eliminated that concern.
* Convenience. The Whispernet is great for when you need the next book in a series right away or want to stock up on a few before leaving on a trip. Being able to have several books stored in the Kindle to take along instead of having to pack an extra bag just for my books for a week's vacation is a huge benefit.
* Aging. I'm 47 and middle age is starting to catch up with me! Being able to select larger print to avoid having to use my reading glasses (just started needing them this last year) and having a device that's easier on my hands for holding to read is a boon.
* Less waiting for publication. I don't like reading hardbacks because of their size and weight. But it's agonizing to wait for the latest book in a series to finally come out in mass market format. Now I won't have to wait!
* Environment. The majority of books I buy and read I'll only read once. I feel guilty about the trees needed to make the paper and all the other energy used to produce and ship/distribute the books required to satisfy my reading appetite.
* Saving Money. While the cost of the Kindle up front is steep, in the long run it will pay for itself and save me money since I read on average 8 books a month. With the free classics available it's also going to encourage me to expand my reading material, for no additional cost.My Kindle was one of the ones that shipped without being pre-registered to my account. After I plugged it in to my USB hub on my computer to charge the battery (the charging cord design is very clever!) I read through the introductory portion of the user guide which told me how to register the Kindle. I followed the instructions and a couple minutes later I was all set!
I thought it would be fitting to christen my Kindle with the Stephen King novella UR, so went to the Amazon site on my computer and clicked on the button to buy it. As soon as I'd clicked the button to confirm my order it appeared on my Kindle almost immediately! I read it while the Kindle finished charging.
First impressions:
When people say the Kindle is sleek they ain't kidding. Everything is very nicely laid out and it just feels and looks cool!
After reading through the introductory guide that loads up automatically at the start and following along it took me almost no time to learn which buttons are where and what each of them do. The intro guide is plenty to get started and I haven't felt a need to work my way through the more detailed guide.
The 5-way controller is teensy! I was a bit taken aback at first by this. Though after a bit of practice it's surprisingly easy to use. For people who have dexterity issues it could be a potential stumbling block. If that's you I'd recommend seeing if you can find someone with a Kindle 2 to try it out for yourself first to see how it works for you.
Being able to change the font sizes is awesome! It's done on the fly with just a couple button clicks.
When starting to read for real for the first time I was VERY aware that I was reading on an electronic gadget and was a bit disappointed that it didn't immediately "disappear" as per the advertising. However, it really didn't take too long for that feeling to lessen. I imagine once the Kindle is no longer my exciting new toy and is just what I use to read books that I'll have completely lost the gadget awareness thing.
It took very little time to get used to having to push a button to turn pages and the screen flash as they turn only really startled me the first few times. I can see how it might bother some people, but it was a non-issue for me almost right away. The page turns are very fast.
The Kindle design allows for holding it in several different comfortable positions with either hand. Normally when reading books I only like holding them in my left hand and during a long reading session it often starts to get uncomfortable, or even painful. I found myself easily switching my Kindle off between hands and into different positions in each hand without even really noticing I was doing it.
I ordered the Amazon case and am quite pleased with it. It's fairly sturdy, looks and feels well-made, and the design is perfect for how I'll likely be using the Kindle most of the time.
Unlike a lot of people in these reviews I think having the case as a separate purchase right from the start was a good move by Amazon. If a case was included, as with the Kindle 1, that would have been reflected in a higher price. But I'd imagine that probably 50% or more buyers end up buying a different case they like better, which means you end up paying for two cases. The way it's been done with Kindle 2 means you can pick which case you want right from the start and only pay once.
Overall I'm thrilled to finally be part of the Kindle community and expect to be spending many, many, many pleasant hours absorbed in books on my new best friend. Kindle me, baby!
Update 3/23/09:
I feel a bit guilty adding more to an already long review, but felt that since I've now had the Kindle for almost a full month it would be appropriate. I'm completely in love with my Kindle!
Like pretty much everyone else I feel that the Kindle 2 is in dire need of a user customizable folder system for organizing books. That's the biggest negative for me so far.
The dictionary function is absolutely fantastic and now that I'm accustomed to having it I found it's frustrating to be reading a paper book and not be able to use it!
I didn't think I'd be using the highlight and note features much or at all but actually have been and they're an extremely nice extra. People in book discussion groups would find these to be a huge benefit.
The search function is also surprisingly useful for a wide variety of uses.
I've definitely lost the gadget awareness thing. This is just how I read most books now.
One of the unexpected great things is not having to deal with my bookmark falling out and having to find my place again. Or being able to just set the reader down for a couple minutes without bookmarking or losing my place because I bumped the book and it closed. It's little things like this that really elevate the reading experience.
Update 6/22/10:
Yes I'm back to add even more! I can honestly say the Kindle is one of the best purchases I have ever made. I haven't read a paper book in over a year.
The reason for this update is because I now have the 2.5 software upgrade and wanted to comment on it.
As I mentioned previously, the Kindle was in dire need of a way to organize books and documents. We now have it in the form of Collections, which is a tagging system. I think it could have been implemented a bit better, but I don't know what sorts of constraints the designers are under. Even with its limitations it's still a HUGE improvement to the Kindle and corrected the one glaring flaw it had.
The Collections are all managed on the Kindle, no computer or software needed. It's very easy to create (or delete or rename) collections and to move books between them. You can name them whatever you like, have as few or many as you like (or none at all if you don't want them). Books can be put into more than one Collection. You can't make nested or sub-collections. Your collection info is backed up on the Amazon server just like the rest of your book info, such as last page read.
Other features added (all of them are optional):
Password. This is most useful for those who want to keep confidential documents on the Kindle. The password has to be entered to return from sleep mode or to access the Kindle from a computer. That's a bit of a hassle for reading at home, but provides excellent protection when traveling or for other uses.
Social networks. You can now send passages you have highlighted in a book you're reading to your Facebook account or Twitter. (I don't use either of those services, but some who use the feature say it's pretty neat.)
Larger fonts. Two new font sizes were added (for a total of 8). They are Humongous and Gargantuan (my terms). For anyone who has failing eyesight and is in need of text that large I'd recommend getting a DX for the larger screen. On the largest font size on my small Kindle there are only 5-8 words on the entire screen. Yeah, it's that big!
Sharper font display. My Kindle has always had a pretty good display and I never had the problems that some units did with greyish text or lack of contrast. I can discern a small difference though and it's definitely an improvement, most noticeable on the middle font sizes.

Besta CD737 2 Way Chinese-English Sentence Translator Electronic Dictionary ReviewHad almost identical device for a year now and found the pinyin input feature useful, but you cannot input the tone for any pinyin - you have to instead choose from a list of characters. Very difficult for a beginner.
This machine will show you how to draw characters with a nice clear animation which also allows you to try with a scribe pen and touch screen. It is good for getting the stroke order correct and clear enough to copy from for written practice on paper.
It allows for english inputs and for character inputs using the scribe pen included. Accurate.
It gives pronounciation guides in audio for most characters, but I don't know how good they are myself. I am told by a Chinese friend that they are fine. She listened to a few.
There is a lot of material aimed at a native of China, but enough is useful to make it worth getting for the serious student. Although it is expensive outside of China.Besta CD737 2 Way Chinese-English Sentence Translator Electronic Dictionary Overview

Sony Reader Touch Edition - Red (PRS650RC) ReviewI have had my PRS-650 for about a week now. I have had a chance to play with all the features. I also have owned a Sony Reader PRS-505 for about one year and a half.ERGONOMICS AND FEATURES
The Sony PRS-650, in my opinion, is a beautiful piece of equipment. It is lighter than the PRS-505, weighing in at only 7.6 ounces. It is also slightly smaller but has the same size screen. It has an aluminum case and a matted back surface. The back is less slippery and thus easy to grip.
I actually prefer now to read on the Sony Reader verses a physical paper book. A lot of people will say they like the feel of a book. You will get over that. The Sony Reader is better than a paper book. The PRS-650 is lighter than most paper books. You will be surprised at how liberating this can be. You can hold the thing with one hand in many comfortable positions. Also, the reading surface is flat. On a paper book, the reading surface is curved near the binding, and thus gets unequal lighting. You also do not have to keep an eReader open like you do with a paper book. Turning a page is effortless. The words flow into your mind as if the device was not there. Beautiful design leads to an immersive reading experience. I thought the PRS-505 was well designed for reading. The PRS-650 is also well designed for reading, it just has a ton more features. I do have to say the PRS-505 was better designed for one handed page turns. The PRS-505 had two page turning buttons located on different places on the eReader. This allowed one handed page turns with either hand. The PRS-650 only has one set of buttons to turn pages. For one handed page turns, you pretty much can only use your left hand. The touch screen also allows you to turn a page by swiping the screen. This is cool, but I don't think it is any better than just pushing a button.
The screen of the PRS-650 rocks! It noticeably has greater contrast than the PRS-505. And the PRS-505 was considered the "gold standard" of readability. The earlier touch models (PRS-700 and PRS-600) compromised contrast and glare to provide the touch screen. With the PRS-650, Sony has solved that problem. It looks great and glare really is not a problem. Also, page turns seem to be about 50% faster than the PRS-505. In the PRS-650, you can also change how the text contrast renders. This works good for books that have colored text that don't look as dark as they could be.
I will not go over all the features, but will point out some that the PRS-650 has over the PRS-505. The one feature I love the most is the ability to highlight text. With a touch screen, this is almost like doing it on a paper book with a highlighter. You can use your finger, but the provided stylus works better for small fonts. You can then associate a note with the highlighted text. This note can be hand written where you can draw with the stylus, or you can use a touch qwerty keyboard. If the highlighted text has a note associated with it, a little icon shows next to the highlighted text. When you touch the highlighted words, the note opens up. I read a lot of non-fiction books that I want to highlight, so this is huge for me. You can also mark up a book by drawing right on the page with the stylus. You can circle things, make arrows, etc., with the stylus or your finger. Pretty cool!
The other feature I love is the ability to zoom on a page. I have read books on my PRS-505 that have had diagrams that I just could not make out on the 6" screen. Now with the zoom, I can see them clearly. The PRS-650 has a cool feature where you can double tap a picture in the book and it will zoom to fill the screen with just the picture.
Another feature worth pointing out is PDF reflow. This is not new to the PRS-650. If you read a lot of PDF documents, this is huge. Without PDF reflow, one PDF page will fill the screen. It generally will be too small on a six inch screen. To read it, you will have to zoom and pan. Pretty much unworkable. The Kindle does not have PDF reflow. With PDF reflow, you can change the font size and the document reflows within a page. So now one PDF page may take more than one screen to render. You do normal page turns to access the reflowed text. This makes reading PDF MUCH easier. A lot of books from the public libraries are still PDF, but ePub is the dominant new standard used by the libraries.
There is also a Power Management feature on the PRS-650 that is cool. When you shut off the PRS-650 by sliding the switch at top, it really puts the device in stand-by. This allows the PRS-650 to very quickly come back on. In stand-by, it uses a very low amount of power. If you never turned a single page, the PRS-650 will lose its battery charge just by being on stand-by. This stand-by time is about 2 to 3 weeks. With Power Management turned on, if on stand-by for more than 2 days, it will fully shut down automatically. When fully shut down, it will not use any power, but it will take about a minute to turn on. You have the option to shut off Power Management.WHY BUY SONY
Many will choose an eReader based upon availability of books, price of books, ergonomics/ease of use, and features. I would like you to also consider and additional reason: principles.
Sony has embraced opened standards on both the format of the eBook and the Digital Rights Management (DRM). They have done this by using Adobe eBook Platform as their underlying technology. Adobe eBook Platform consists of several components, most importantly Adobe Digital Editions and Adobe Content Server 4. Many other publisher and retailers have also chosen to use Adobe eBook Platform, which has resulted in improved compatibility between eReaders and eBooks.
Sony Reader Store, Borders, over 9,000 public libraries, eBooks.com, Books-A-Million, to name just a few, have adopted Adobe eBook Platform. Barnes and Noble also uses Adobe technology, but uses a DRM variant. The Sony Reader PRS-650 can read protected eBooks purchased from the above mentioned retailers, with the exception of Barnes and Noble. The Barnes and Noble Nook can read books purchased from Sony Reader Store, but surprisingly, as far as I know, the Sony Reader cannot read protected books purchased from Barnes and Noble. I suspect a firmware update to the Sony Reader allowing support for the DRM variant could change this in the future.
Other eReaders that use Adobe technology can read the books you are reading on your PRS-650. Most notably is the Kobo. The way you can tell an eReader is compatible with the Sony Reader is if it supports ePub for Adobe Digital Editions and PDF for Adobe Digital Editions. This specifies the document format and DRM standard.
The key to make this all work is to use a consistent Adobe Digital ID. When you get your PRS-650, you will be asked to create an account on the Sony Reader Store. Typically you will use an email address and a password to create an account. Sony Reader Store will generate an Adobe Digital ID based upon your Sony Reader Store account credentials (provided your computer is not already authorized with an Adobe Digital ID). It will then authorize your computer and your device based upon this Adobe Digital ID.
Now say you want to purchase a book from Borders. This can be confusing, but as long as you remember to use a consistent Adobe Digital ID, you will not have compatibility issues. Your Adobe Digital ID is essentially your personal encryption key used to protect your copy of eBooks. Borders will recommend that you install Adobe Digital Editions and their reader app. You do not need to do this. The Reader Library software that comes with the Sony Reader, along with the Adobe Digital ID generated by the Sony Reader Store, is all that you need.
When you purchase a book from Borders, and then download it, Borders will actually download a very small file with an acsm extension. The Reader Library Software can open the acsm file. When the acsm file is opened by the Sony Reader Library, this causes the download of the actual eBook from an Adobe Content Server 4 server. At the moment of download, the eBook is encrypted using the Adobe Digital ID associated with your authorized computer and by Sony Reader Library software.
So my advice is not to install Adobe Digital Editions and to use the Adobe Digital ID generated by the Sony Reader Store. When you get set up to check out books from public libraries, OverDrive will advise installing Adobe Digital Editions. You do not need to do this. The public libraries work exactly like Borders. The public library will download the acsm file to your computer, Sony Reader Library will open the acsm file and download from the Adobe Content Server 4 server your encrypted version of the eBook. You actually can do all this without the Sony Reader Library software and just use Adobe Digital Editions. You can let Adobe Digital Editions generate your Adobe Digital ID, but I personally prefer the Sony Reader Library software just because it makes purchasing books from Sony Reader Store very easy. The Reader Library software also works great with the public libraries. You can return your book directly in the Reader Library. The Reader Library will tell you how many days are left on your check out. The Sony Reader PRS-650 will also display days remaining for your checked out book. When your check out expires, the book will be removed from your computer and eReader automatically.
So if you want to share books between eReaders, use the same Adobe Digital ID. You can have up to six devices on the same Adobe Digital ID. My wife now uses my old PRS-505 and we can easily share books.
So I started this whole discussion around principles. Say you bought a Blu-ray player from Store A. Store A then says, your Store A Blu-ray...Read more›Sony Reader Touch Edition - Red (PRS650RC) Overview

Sony Digital Reader Touch Edition - Red (PRS600RC) ReviewI have been following the e-book readers for some time, and I wanted several things for me to "jump on the bandwagon." ***Since I have received many questions, I am now including a video to demonstrate my favorite features***
1) I have a number of PDF reference books, so a Reader needs to handle these well. Since my books are text, these reflow well on the Sony.
2) Because I will use (and now am using) the Reader for reference books, it was important that I be able to access my notes directly from my computer to use in other documents. I actually began using the software on my desktop several months before I purchased the 600, and was pleased with its capabilities.
3) I enjoy the free epub books from my library. The Sony accesses these easily. There are also a number of locations besides Sony selling the epub or Adobe digital books (usable by the Sony Touch) giving me more choice in my decision.
4) The Touch handles my regular documents well - as a public speaker, I love having my speeches available to study on the reader, without having to print them out!
But for those looking for the points I already love (thus the 5 stars)
1) I love having the touch turn capability, just a brush of my thumb!
2) I enjoy the sideways and zoom features for PDFs that you want to keep "standard"
3) After only a couple of minutes, I forgot I was even using a reader and I got involved in the book.
*** I live in an isolated area - so neither Whispernet for the Kindle nor the upcoming 3G connection on the more expensive Daily model would be helpful - I'm just as happy to order my books "in advance" and carry them with me.
I enjoy the feel of the Reader by itself, but since I will be carrying this "library" with me, and I was worried about protection, I purchased the M-edge Executive Jacket for Sony Reader PRS-505 (Genuine Leather--Pebbled Grey w/ Black) - SALE! which fits it perfectly.
I also purchased the Sony AC Charger for PRS505SC and PRS505LC to ensure that I can charge up my reader when my computer isn't around.
Edited after 2 weeks and 10 books
Some people have mentioned the glare - since my previous reading was on my laptop - this isn't an issue for me. I keep my lighting at my side, and it is not a problem at all. It is more noticeable in a dark room with a single light source.
Another issue I have encountered isn't with the reader - but with the interaction between Windows and the software. It is pretty touchy. I have learned to be careful of some PDF documents which have caused problems.
It is also important that when importing books that aren't loaded through the reader that you "maintain" the link by not moving them once they are imported. Like Powerpoint and other programs, the desktop ebook reader doesn't store the book in the program - it links to it on your computer. Breaking the link means it can't find the book - and it can't upload the book.
*** A special touch for a "Grandma" is the ability to be able to load photos of my granddaughter to carry with me. There is even a feature that permits showing the photos as a slide show. While the photos are in black and white, they are very sharp and it is a nice touch when I travel.
*** Edited after 2 months -
A recent update in the software has removed some of the software connection problems I originally experienced. So, that's a plus!
However, I have recently added some PDF files that did NOT flow the same way as my original "professional" files reflowed. After checking with those more knowledgeable, I have been told that the problem is not with the Sony, but with the way the PDF files have been set up. The PDF is supposed to include "tags" that will help the pages to reflow correctly. My recommendation is that anyone with PDFs they need to carry on the reader download the free computer software and attempt to read them using this software. If it works on your computer, it will reflow correctly on the Sony. If it does not - then it will not do so on the Reader either.Sony Digital Reader Touch Edition - Red (PRS600RC) Overview

SuperTooth Z004092E High Definition Bluetooth Portable Visor Car Kit and Speakerphone for Cell Phones/iPad 2/iPhone 3/3G/3Gs/4 - Bluetooth Speakerphone - Retail Packaging - Black ReviewSUMMARY:
=========
[I am using the Supertooth HD with a Samsung Focus running Windows Phone 7.5 (Mango)]
If you search my reviews, I bought and returned the Supertooth Buddy (the little brother version of this). So far, the Supertooth HD has not exhibited any of the annoyances of its little brother. Currently, this is a 5-star device and I will update my review as needed.
What makes the perfect car bluetooth speakerphone?
==============
1. It should have caller-id that speaks the name of the caller
2. It should automatically turn on/off as you are away from the car
3. It should have ample volume while driving at highway speeds
4. You should only have to press a single and easily accessible button to answer or place a call
5. It should make use of your phone's built-in voice recognition system (if your phone has this)
6. It should be easy to pair and auto-download your phone's contacts
7. It should reconnect easily when you are in the car
8. Callers should be able to hear you clearly at highway speeds
9. The charging port should not be obstructed when the device is installed on a sunvisor
10. It should have a long battery life
11. It should be reliable whether it is -40 degrees in Fargo or the internal car temperature reaches 140 degrees in Texas
12. It should have good documentation or manufacturer's website and support
13. It should be usable whether the sun visor is flipped down or up
14. It should be reasonably priced
How does the Supertooth HD stack up?
=====================================
A. As of 10/2011, I believe the Supertooth HD meets the bar on all of the items above except #11 is currently unknown as the weather has been mild and #12 - the company website leaves a lot to be desired (poor resolution graphics, non-working hyperlinks, the support phone # is a long distance call to France, and the download for the "Full User Guide" says "Coming soon....")
B. I've owned the Motorola T505 and it does not have spoken-name caller id, doesn't turn off or on automatically, the volume is not loud enough at highway speeds (or heck, even idling), and it is difficult to press the small answer or call button. I got it a couple years ago and I believe I threw it in the trash.
C. The Supertooth BUDDY that I returned does not have ANY form of caller id (it just rings), the bluetooth would never turn off when I was in the house, and it wouldn't always reconnect reliably. I also had one strange charging issue before I returned it.
D. I've owned TWO of the Motorola T325 which was almost the perfect device, but horrible reliability. Two broke and they were returned to Amazon. I suppose they simply couldn't handle the Texas heat. They would connect/disconnect constantly and or wouldn't hang up or wouldn't place a call or wouldn't turn on.
E. The Jabra Freeway is almost twice the price of this (I've never used one), but the reviews so far aren't all 5-stars, so I decided to take one for the team and try the Supertooth HD.
F. I purposely purchased the Jabra Cruiser2 (similarly priced to this) for my wife, so we could decide which one we liked better in 30 days. So far the Supertooth HD is ahead because the Cruiser2 doesn't seem to automatically turn on (you have to remember to press the 'phone' button to make it reconnect, though it does connect very quickly) and caller-id wouldn't work for my name, even though it worked for other spoken names. It would only read my phone number, not speak my name, even though her caller id display clearly showed my name. We re-downloaded the phone book and the Cruiser2 still does not like me. So the Cruiser2 is losing in #1 and #2 in the list above and fails in #13. The Supertooth Buddy and HD are the only genius devices that use magnets that allow you to quickly move the device to the front or back of the sunvisor for when it is flipped down or up.
Usage Notes:
=============
Since the company website has "Available soon..." for the full user guide, here's what I've figured out on my own:
Saying "Voice-dial" is the same thing as hitting the voice-recognition button on your phone. You say voice-dial and then it loads your phone's personal voice-recognition system and everything works normally from there. With Windows Phone 7.5 Mango, I can listen to as well as dictate text messages from the bluetooth speakerphone - it's pretty fantastic!
Beyond that you have to specially add an extra phone entry to your important contacts, so that even if your phone does not have voice-recognition dialing, the Supertooth HD will pick up on the special entries and still allow you to use the HD's voice-dial, pretty slick. So what I'm saying is that you can call contact 1 or call voicemail from the Supertooth HD's own voice system or you can say voice-dial, let your phone's native voice system take over and THEN say, Call Mary or Call Voicemail. Both work great.
Now even if you don't have Windows Phone 7.5 Mango or a fancy smartphone, you receive 6 months free of Dial2Do which is basically a special phone number that you call that allows you to send text messages, emails, Facebook status', tweets by voice. You have to previously register the numbers or addresses on their website, etc).
IN CLOSING:
============
The Supertooth HD almost meets the bar on becoming the perfect car bluetooth speakerphone and for the price and 6-month trial of Dial2Do, it is definitely a great buy.
I will update this review as the days pass if I encounter any reliability issues or any other annoyances.SuperTooth Z004092E High Definition Bluetooth Portable Visor Car Kit and Speakerphone for Cell Phones/iPad 2/iPhone 3/3G/3Gs/4 - Bluetooth Speakerphone - Retail Packaging - Black Overview

Lingo EuroTalk Translator ReviewI bought this on another site before I saw it on Amazon. Paid $10 more for it. I bought it because I am going to Athens in March 2011, and it has the Greek language as well as French Italian Spanish and German. I'm a 67 year old retired male, and this is my first time to travel abroad. I have traveled all over the U.S. for the past 10 years, and decided this year I'll try another country. I am going to stay in Athens for 6 days and rent a car to see Sparta, Delphi, and Mt. Olympus. I have a GPS that speaks English, but by traveling in some remote areas of Greece, I'm sure I will need a translator. I have researched many kinds before I decided on this one. I've had it for a couple weeks now, and it seems like it will work for me. It has a storage for instant recall of favorites, so I am entering phrases I think will be helpful, and will play them back, like before I enter a restaurant, and have them fresh in my mind. It not only speaks, but shows typewritten in the chosen language, as well as English. It helps when hearing the spoken version to see it written in my language. Sometimes what may sound like a "g" could be a "t". It will only accept and repeat back single words, that you can choose. Would be nice if you could type in a whole phrase of your choice. It does have many, many, pre-selected phrases arranged in categories though, and I do have a couple months to choose and select, then place them in favorites. If anyone could advise on the best way to understand their reply please let me know. I am going to try to guess at their response then type it in English and listen to playback in their language. Will have to familiarize myself with single, common words. That's where it would be nice to be able to type in a phrase and translate it. Sometimes words that are said in phrases are pronounced entirely different. Anyhow....this seems to be a very good translator for the price. It came with a quick start, and an in depth manual, an earbud, and a Greek alphabet punchout that can be placed and removed over the English keyboard. As far as the vocal playback. It's pretty good. Any foreign language will sound strange when you hear it, that's why the typewritten part is nice. You can read along in English as they speak in their language. makes it easier to understand.
Again, I think it's a pretty good little product for a soon to be world traveler. Who knows, next year it might be Rome.
Hope this take on it helps.Lingo EuroTalk Translator Overview
