John Colapinto is a best-selling author of non-fiction books, including How Nature Made Him, and novels, including Undone. But he doesn’t think he could have written those books until he abandoned his manual typewriter and switched to a computer. He talks about how he started his career hammering out magazine articles on the typewriter, how he thinks that shaped his writing for better and worse, and how the typewriter shaped the work of James Joyce, Ernest Hemingway and Jack Kerouac.
