It seems that e-ink have actually produced a product... But after so much time things have moved on a bit. And $3000 plus tax is a bit steep for my wallet. I actually don't care about colour that much, its the low power consumption and high resolution that are the exciting things.
For most common computing tasks (reading email, browsing the web) there is no need for animated, full colour displays. I'd prefer a computer with a 12" screen and full QWERTY (or Dvorak) keyboard that folds up to fit in my pocket, with a wireless card and a Li-Ion battery that lasts a week every charge. And it should be cheap ;-)
