As some one said(I forgot the reference ), it's not Flat design, it's flatter than previous version.
I agreed with "I think iOS 7, on the whole, looks worse than iOS 6." The icons look weird, and most of all, harder to be recognized than pre-version, that's why they lose their elegant.
I prefer to say, Flat design does not mean a flat element, flat appearance, flat interface. We should feel flat, the interactive should be flat, not just only our eyes see it is flat.
