"Extremely versatile, for real readers."4.0 starson by micklest
Pros: Multiple doc formats, Public Library lending-compatible, Audio, Ease of use, sleek design, Notations, text and handwriting memos, built-in dictionary, scalable text, rotatable screen, "Go To Page...", more.
Cons: Screen contrast could be a bit better.
Summary: Aside from the slight contrast/glare issue, the Sony Touch trumps the Kindle 2 for me in so many ways. Primarily, I don't have to BUY every book I want to read; I can borrow e-pub books from my local library online! Feature-packed and pretty easy to use, once you get the hang of it. Glad I bought the Sony Reader Touch. I don't really need the Wi-Fi feature of other readers.
A word about Google scanned books: DON'T. I find that Project Gutenberg has done a much, much better job with scanned public domain texts. Too many Google titles have wonky characters or worse. Sometimes Google even gets the title wrong! I downloaded Hugo's "Notre Dame de Paris" (aka "Hunchback of Notre Dame") and it turned out to actually be "Les Miserables!" ProjectGutenberg.org has been at this longer and does it best, and now carries ePub format. I'll never go Google again for free scanned e-books.
