There's no question that many of the fundamental capabilities and user interface approaches in Google's Android bear a lot of resemblances to what's in Apple's iOS. In some cases -- such as the basic gestures, the use of app screens, and email client layouts -- the method has a history predating both products, while in others it's easier to see direct imitation, such as in the use of the app store and the .com key.
But Android is not merely a clone of iOS; it has its own unique capabilities and interface elements, such as its voice-based Web navigation. And in some cases, Apple has been, shall we say, inspired by Google's previous choices. The inspiration in both cases is not limited to each other; both borrow from Windows and Mac OS X, as well as from the defunct WebOS (which also borrowed from the same sources).
Still, as the two big mobile OSes, Android and iOS are what most users see and compare. Herewith are the iOS capabilities that trace back clearly to Android.
