The theme is clear: iOS 7’s UI requires some of Apple’s biggest
strengths, and efforts to copy it will be hindered by some of
Android’s biggest weaknesses.
iOS 7 is also going to be a problem for cross-platform frameworks.
Fewer assumptions can be made about the UI widgets and behaviors
common to all major platforms. And any UI targeting the least
common denominator will now look even more cheap and dated on iOS
7, since the new standard on the OS is so far from the old one.
