Take one E Ink AM300 prototyping kit, combine it with a build of Mozilla's new Fennec mobile browser, and this is what you get: a touchscreen demo of web surfing on an e-ink device. It's the work of Jaya Kumar, who loaded Fennec into the AM300's Linux-based Gumstix controller and, with only a little modification, has a usable browser.

Right now memory seems to be the constraining factor; in the second video below, you can see how fast the Midori-webkit-gtk browser runs on the relatively meagre Gumstix computer. The Gumstix E Ink provide has a Marvell XScale PXA255 processor together with a Bluetooth transceiver, USB, a serial port and an MMC card reader.
Next up is enabling some form of on-screen keyboard, which requires getting hildon built. Then he'll be able to use it without any form of external keyboard.
