Saw Russ Wilcox, the CEO of E-Ink, at O'Reilly's TOC conference in February, and he was saying to expect color e-ink in December 2009 or early 2010.

PlasticLogic (http://www.plasticlogic.com/product.html) is made of bendable eInk and has a touchscreen. I got to mess around with a prototype of this device at O'Reilly's TOC conference in February. When I asked why the device itself was not flexible, they said that in consumer testing, they found that people didn't like the flexibility because it made the device seem more fragile than it really is. The touchscreen was pretty cool--they use it to have an iPhone-like soft keyboard, which means you can have a much bigger display area, as you don't have to find somewhere to put all those keys, like on the Kindle.
