Well, with an Audible subscription, that book is 1 credit, which is somewhere in the neighborhood of $10. Speaking of which, I'm disappointed that audiobooks weren't broken out in the story - anecdotally, I know more people that listen to Audible/audiobooks regularly than use a Kindle (somewhat naturally, since most people carry a phone everywhere). So I sort of question the implication that people are returning to paper when a rising category has been excluded.
