I am new to the forum. I am now using Cybook Gen 3 and I am happy with it so far, since there were no problems in more than two months. Previously I was struggling to read on my desktop with Microsoft Reader, and was much happier when I could read books in Mobipocket and E-Reader format on my PDA (Fujitsu). The only problem was the battery which tended to go out while I was far from home.
Cybook is great, and my only problem with it is that I need light to read (I would prefer backlight). I expect e-books to be better over the years and believe this forum could help.
