Have one and LOVE IT! It was a gift. I had been one to swear I'd never use such a device. To disspell a few misconceptions: As for the battery issue, it can go two weeks without being recharged. As for the screen issue, it's not a computer screen. Doesn't resemble it at all. It's called e-ink, very easy on the eyes, actually more-so than print, and you can adjust the font size.
Still love my print books, but I see a bright future for these things co-existing, and because of cost and delivery I always see if a book is available in electronic format first.
