Most of the ideas being "copied" by one company or another are all common sense things anyway. But whoever does it second is considered to be stealing. Android initially ripped off iOS, that's kind of a no brainer. But since then it has evolved. A lot. I don't think the two OS's look or behave anything alike. And at the end of the day, most of us are just using these phones as a means to access apps, and the App store/Google Play store are almost identical at this point.
Honestly, I think iOS 7 looks great for the most part, but the only real new feature that I find interesting (and don't find on Android) is Air Drop. But no matter what iOS does, you can count on a thousand developers releasing apps for Android to mimmic iOS behaviors. And since Air Drop will be an iOS only feature, it looses luster. Just like iMessage and Face Time, etc. I am way more interested in an app that performs across at least the two major platforms than I ever will be in a native OS feature. Apple and Google both aren't going anywhere any time soon, and neither is Samsung. Until the whole world is using the same hardware and software, there is no wowing me with exclusive features. It's not like the old days anymore where every smartphone was a Black Berry.
Have you never heard of WiFi direct or NFC file transfers on android? Android from the first moto droid 1 supported dlna and could connect to any device or computer other then an Apple locked down system and could look at the whole hard drive on the computer and play,move copy movies,mp3 or what ever you wanted with ease.
Air drop is nothing compared to android NFC,WiFi direct and dlna file sharing
