A key driver to e-music's growth has been the availability of slick portable devices. E-books, in contrast, have no decent rendering device and have to contend with a wonderful physical alternative, the book. (Sorry, PDA screens don't cut it.) Now imagine an Apple iBook -- polished exterior, hundreds of e-paper sheets that can dynamically update to your current book selection, autosyncing with iTunes -- and what that would do to the e-book market. Would you migrate some portion of your physical library to an e-library? Would you start to explore the long tail of fiction outside the traditional publishing venues? Do you think there is a fundamental difference between books and music, say length, required concentration, or home decoration?
