I know of three: Sony Librie: 1st attemp, not bad, but so DRM riddled that's unusable. You didn't purchase a book. You rented for 3 months, and the cost is similar to death tree A prototype made by e-ink engineers. I don't have a link, but It was in /. not so long ago http://www.jinke.com.cn/english/index.asp. Very similar to Librie, but, run on linux and has an aditional LCD display for commands (e-ink is loooooow)
