I'm a non-demanding e-book reader. I think in the past three years there's only been one e-book that was so poorly proofed that I couldn't get past the first chapter. I don't mind typos, I have no need to annotate, I don't need a dictionary... Once in a blue moon I come across a book that has all the apostrophes replaced with question marks. For some odd reason, that bothers me enough to put the book into a program with a 'search and replace' function, but then I'm good to go on. I read on a Sony 505 that has no touch screen, no backlight, just an old reliable e-book reader that I take with me where ever I go. I hope it lasts forever cuz I just hear waaaay too many problems with all the newer, better readers available today.
