I used to have one of these: http://en.wikipedia.org/wiki/ILiad http://en.wikipedia.org/wiki/ILiad The iRex Iliad had a big screen and you could write on it with a stylus. It ran linux and didn't use proprietary file formats, so was great for actually doing stuff. BUT The refresh rate on the screen meant that doing anything with the stylus was painful. It lagged way too much. I see nothing in the specs for the sony device that refers to this problem with e-ink, and no video demo. Anyone have better info?
