By now, we've all gotten pretty used to not owning stuff-at least in the traditional, hold-it-in-your-hands sense. If you're anything like me, your DVD collection stopped growing a few years back once Netflix and Hulu bolstered their offerings. And that CD storage stand (hell, even your iTunes account) has probably gathered dust thanks to Spotify and Rdio. But books? Turns out, we're still content to pay $10 for a paperless novel that we're not even certain we'll like or finish.
