Well, we'll see. But if you do an analysis of how many phones have a droid operating system, as opposed to an Apple operating system, chances are that far more will be Droid because Droid is installed on many different manufacturer's devices (phones, tablets). Same thing happened with Windows for desktop computers. But again, we'll see. I only know why Window buried the Mac OS on desktop computers, even if the Mac was a more stable OS.
