I predict that iOS 7 is going to be the Vista of Apple.
I hate the icons. They look like something out of an unpopular jailbreak theme. No class at all. Jony Ive needs to go back to working on hardware and then need to hire someone who understand software usability.
I really don't care if you guys think that skeuomorphism is not chic or hip anymore. It lends itself toward usability because user interfaces are for the "user", not the hipster wannabe designer. Usability sometimes requires a few compromises for a designers "vision".
Even these icons use skeuomorphism because without it, you would not recognize which is the phone icon.
See this article on what it is any why it can be useful.

That design philosophy is context sensitive where the look and feel is suited to the context. The current design language in iOS 7 is not context sensitive. It is harder to use for new users and is really boring visually IMHO.
