I wonder what kind of interesting applications could be done on e-ink harnessing the advantages of the long battery life and not suffering by the slow refresh rate. Sure, porting doom or implementing a terminal is an interesting and probably challenging feat, but still it's applications that don't shine on an e-ink device.

Maybe some "slow" strategy game, that updates upon certain events but might remain unmodified for hours at a time? Or - more in general - an application that is required to be on for a long time but really doesnt' change often.

I think eInk price labels are now getting to be quite a common thing in some stores - while it's probably not fair/legal to change prices while the store is open, it means prices can be updated very easily overnight.

A traditional roguelike, in the line of TGGW/Cogmind/Nethack/Brogue/DCSS, would probably be nice. Not really a "slow strategy game", granted, but the fact that animations/colors aren't necessary makes it a good fit IMO
