When Jack Kerouac wrote On the Road in three weeks, he typed it on one long scroll of paper so he wouldn't have to slow the writing process. He probably never suspected that someday we'd read our books the same way.
But turning pages, as it turns out, is a very 20th century (and 19th and 18th, come to think of it) behavior. It gets in the way of our reading just as much as it did with Kerouac's typing. In the tablet and smartphone world, scrolling makes more sense. Magazine apps discovered that a long time ago. Why not e-books?
