There are some things I think this needs before it's perfect.1) Nothing replaces a paperback until I can read with it in the tub. I don't necessarily expect it to survive me dropping it in the water, but it needs to survive the intense humidity of the tub-reading experience. The device would therefore need a seamless case, with pressure-sensitive regions for buttons (depressable regions would be nice, for feedback).2) It would be nice if the screen could illuminate. I know the e-paper doesn't work with back-lighting. But some form of illumination across the face or from in front would be great. Heck maybe even a place to clip a light for it.Otherwise I think the Kindle is great.
