That's because no-one's ever given us E-paper. I don't want or need a whole forest of paper to be re-used after a single day (or whatever arbitrary number they set). I just want a single big sheet of foldable, high contrast (equivalent to todays paper-paper) E-paper that I can re-use whenever I see fit. I need it to be able to update wirelessless whatever data I happen to want (e.g. page 7 of the NYT), through a simple interface. And I need it be inter-active. If I double-tap a word, for instance, I want it to provide me with a definition, or perhaps wiki article, about that word. This reusable paper doesn't even come close.
