I agree with points one, two, and five especially. If iBooks is going to be skeuomorphic, it should go all the way. Apple tried to hard to make the pages turn realistically but it looks silly that you get to the end of a book and there’s still a stack of pages left.
But what I’d really like to see to see a non-skeuomorphic mode where you just get text over a flat background with no borders.
