I like it in moderation, when compared to the flat and unimpressive nature of things like Windows Phone, I feel a little depth is necessary. But things like the Address Book on Mac OS X and Game Center are just too far. Passbook is always mentioned, but I think that is a bit more useful. Knowing what is a "Ticket" or a "Coupon," because they actually look like that. The Shredder is cute the first time, but I suppose it doesn't really get in the way. I really like the design language of the new "Music" app on the iPhone, I hope they carry that over to the rest of the OS. I just want some more consistency.
