I would definitely suggest trying to find one to try out. (Or maybe seeing if it's returnable if you don't like it?). I've tried both the Kindle and the Kindle 2.0, and the page-turn/refresh rate is still too slow and the organization too...simplistic, for my tastes. I'm holding out for a DRM free e-book reader (hey, a girl can dream), but the page-turn rate is a deal breaker for me, and I hated the feeling of waiting for the next page, or just having to "turn" pages constantly.
But, as far as I know, they work fine here!
I do occasionally read books on my iPhone using Stanza; it's not ideal, but I mostly read the free out of copyright ones (or ones that are free for promotional reasons), and it's a good backup for the times when I have somehow lost my brain and forgotten to bring a book.
