Summary: I purchased this a couple of years ago because of the screen size and number of supported file types as well as the library lending capability. I used it for about 4 months all told before buying a Kindle (which I had strongly resisted). The only problem I had with it was the glare off the touchscreen which resulted in extremely limited viewing angles as well as decreased screen contrast.
Summary: I got this about two years ago, and it saved my butt in class. I had a kindle 1, then got a Kindle DX, which has a huge screen and does the text-to-speech thing (which is great for Kindle books). However, the DX is truly hard to carry around. The Sony Daily edition is the perfect size to read PDFs (tell you why in a moment) and has two cool apps. I read a lot of PDFs, and the kindle never formats these right. So they tend to be hard to read.
Summary: PRO:The device itself is nicely priced for its specs. Larger than average screen, decent memory, and I have had no issues stocking it with books from a third party vendor or my own private collection. Interface is clumsy, but tolerable. Battery life gives me at least a week of heavy use. CON: Sony's "READER" software is an astonishingly clumsy, slow and bug-ridden work of crap.
Summary: THE SONY PRS900 I've had for the past year. It's my first ereader. Not sure if I will continue with Sony in the future or try the Kindle Fire. However, I do like the ePub format. It's a very good quality metal body with touch screen. I do find it a bit slow sometimes going to the main menu. I like the fact that you can view documents or books in landscape or portrait, but I prefer the portrait viewing.
Summary: I bougth this product to can read PDF books. This ereader shows the books just fine, because to me is not a white background. Also it's slow to move to next page or search another book. I think is better a tablet or new kindle, because i prefer read the PDF on my iphone 4.
Summary: bought ths refurbished reader a few weeks ago. Works OK but som trouble with the glare in the touchscreen at some angles. Didn't notice the custom taxes so this went from not so cheap to expensive..if you live in Sweden be aware that you should add an extra 100 dollar at the price. The wifi doesn't work but I didn't expect it to..eg it maybe work but it can't find any store..
Summary: My wife and I got our first ereaders for Christmas, 2010--hers is a Kindle and mine the Sony Daily Edition. We did so as we wanted at least one reader which could get library books for free. I had been using my Sony only for a short time and noticed some real deficiencies right away.
