The dichotomy is what's dangerous. Address Book looks like an book, so I'll try to interact with it like that. When that doesn't work, I get confused, angry, and it's generally a "failure" from a UX point of view.
Neither form of skeuomorphism is inherently bad, but it's easier to shoot yourself in the foot and ruin the UX when you move from decorative to functional.
Yes, I get the complaints about Address Book. But "page flipping in an e-book" is either really poorly written, or was not referring to Address Book to begin with, since Address Book is not an e-book. Hence my question.
