TIL about the PocketMage. This guy is building an eink clamshell PDA kit and it looks super cool.

Definitely going to keep my eye on this PocketMage kit. While not perfect it does look pretty dang cool. I wonder what the actual battery life will be like. Also, if you can plug in a usb keyboard or a bluetooth keyboard it would be nice. I don't love having the real time text entry showing on the separate display before being put up on the main display for longer writing but for short notes and things it's probably fine.
I think a memory lcd/rlcd would have been a better choice for this type of device personally but it's still cool.
