(This is my first post, I hope I don't break any rule)

I'm looking for the TINIEST realistic motherboard and battery to make some kind of e-reader :
 drive a 8" e-ink screen (normal refresh rate);
 high polling rate for the digitizer (>= 180Hz); 
 display e-book on it (zoom, prev/next page, annotations);

 4 hours of usage on battery will be fine. 2 will be ok  (and unlimited if usb powered);
 being able to run app is an option but not mandatory;

Do you know of  some crazy projects (e-watch mobo + lvds driver) I could have a look at ?
