New media don’t succeed because they’re like the old media, only better: they succeed because they’re worse than the old media at the stuff the old media is good at, and better at the stuff the old media are bad at. Books are good at being paperwhite, high-resolution, low-infrastructure, cheap and disposable. Ebooks are good at being everywhere in the world at the same time for free in a form that is so malleable that you can just pastebomb it into your IM session or turn it into a page-a-day mailing list.
