A Pixel Qi display may fit your needs. There's a 10" DIY display available http://www.makershed.com/Pixel_Qi_display_p/mkpq01.htm although you may just want to pressure your favorite consumer electronics company to include one by default.

By the way, the earliest version of the Pixel Qi technology was used by the first OLPC XO laptop model.

Edit: Pixel Qis are not actually E Ink.
