Already bought my second. First was a Sony 500. Currently using Cybook. When will upgrade? Probably when I have the funds and something interesting comes along. But what I really want is a combination of my Cybook's eink (but in color) for reading in bright light, my Palm TX's PDA functions and speed & back light and the ability to fold/roll/or otherwise be made small enough to fit in my shirt pocket. And of course infinitely long battery life.
