There's an intimacy inherent to touching and manipulating a book. I don't know that it's like that, visibly at least, for any other medium. (In particular I'm thinking about the intimacy associated with navigating your own phone or computer, but you can't see any of those familiar gestures taking place. Most of it happens with slight finger-twitches of a cursor, and rapid eye movement.)
