1. A social-enterprise initiative aimed at widespread distribution to the developing world. Textbooks could become universally accessible. Wikipedia would benefit from a more diverse group of content creators.
  2. Color pictures. I want to read picture books, graphic novels, and the Saturday comics on an e-reader. And I want great image quality.
  3. Split-screen language translation. It would be sweet to read the original text and a translation at the same time. Great for language learners, religious scholars, and literary nerds.
  4. Cover art gel skins. Could function as a homage to our favorite books, a community art project, and a way to keep cover art alive.
  5. The ability to “trade” books. Transfer electronic ownership to another e-reader user. This could be used for borrowing books or donating to those in need.
