I like loading books from http://www.booksinmyphone.com/ into my cellphone (its just an ordinary LG, not a fancy PDA or anything like that) to read during my commute (its great and its cheaper than my latte). They've done a really good job with the reader - its easy to read and real easy to use. You can even adjust the font size if you need to. It auto bookmarks when I exit book mode - on my commute home I just pick up where I left off. At night when my partner has gone to sleep, I can read with the lights off on night vision mode. I'm totally hooked!!!!
