Due to the degree that each of the major mobile players "cross-pollinates" or "copies" these days, why are we even still talking about who is copying who? Who cares? Looking at these new iOS demos, I see a lot of things that were first done elsewhere. But to most people (outside of our ivory tower), that doesn't matter, and it shouldn't.
But Apple shouldn't be faulted for some of these "borrowed" elements in iOS 7. Google does the same thing, Microsoft does the same thing, and so does everyone else. In fact, I expect them to copy good things, because I as a consumer want the best for my money. Stay on your own stubborn, outdated path and end up like RIM.
