I think you could argue the control center is borrowed from Android (although the iOS 7 version looks kinda spiffier). The interface for moving between apps is similar. I had to open Safari to see your comparison. The demo I see on the product page for iOS7 reminds me more of Android than Safari. I remember seeing a few other things in the WWDC presentation but I don't remember what they were.

All that said, I hope both sides "steal" good ideas early and often.
