I just had this conversation with my brother, where the SMART idea is for SOMEBODY to build an Android tablet so different but useful that it makes everyone go, "WHY DIDN'T WE THINK OF THAT?" I told him that I would LOVE for somebody (ideally Amazon, given their other products) to design an ANDROID tablet (a proper one) with a RESISTIVE touchscreen digitizer (so you can use either a stylus or finger) that uses a high resolution eInk display. It would be the most AWESOME thing for the Kindle app to run on.. and take ONSCREEN, hand-drawn notes and underlines, marks, etc. It would be able to do INCREDIBLY double-duty as a Google calendar with the ability to do hand-drawn marks, a GREAT way for artists to draw wacom-style on an eINK display with pressure-sensitivity and all (especially if the stylus can report whether the tip is being pressed or whether the blunt end is bring pressed (i.e. pen/pencil/spray vs immediate eraser). Since it's an Android tablet, it COULD run/do anything a tablet could do (although playing video would be awkwardy slow--but they HAVE managed to get around upwards of at least 15fps with eInk lately). The eInk guys have even recently begun making COLOR eInk screens (although the few devices made seem to make it look like it's a bit washed out--but it's still early). Imagine the INCREDIBLE battery life on such a tablet!
