This Ian Bogost essay on e-books is an oddity, in the sense that about a decade ago we had thousands of essays on this same theme, but have had very few since. That, I think, is because everything got hashed out back then as thoroughly as it is likely ever to be. I am not sure what Bogost’s essay adds to that long-ago conversation, but I know the chief thing it neglects: eyesight. Many people who love codex books (myself included) read e-books when the combination of poor eyesight and poor book design makes reading a given codex painful or even impossible.
