The Guardian (back in April) took a peek at the Librie EBR-1000EP which costs c. 220 pounds (only available in Japan at the moment) and sports a 6in screen with a resolution of 600×800 dots at 170dpi, (better than the 70-90dpi of a regular computer display). It’s using the microcapsule display technology pioneered by “E Ink”:http://www.eink.com/ working with Sony and others.
It’s potentially a very exciting development – it’s a pity that according to “a recent review in Fortune magazine”:http://www.fortune.com/fortune/peterlewis/0,15704,685443-1,00.html Sony predictably enough married this potentially revolutionary technology to a boneheaded copy protection scheme.
