It may be important to remember that flatness is not something that came out of Apples labs. To the contrary, the 'clickable' look on buttons was invented at Apple (Xerox had flat buttons). And the reason, surprise, surprise, was and always has been usability. I don't see them reversing that any time soon. That skeumorphism has seriously gotten out of hand in iOS 6 is a different debate. Ive will fix this.
