Earlier quoted context omitted.
Yes, but that does not invalidate the data presented here. It is worth comparing smartphones, to see how others are fairing in this market segment, and it is worth comparing entire OS marketshare, to see what everyone is using. Apple is doing well, and Android is doing amazingly well.
I don't know about amazingly. It seems entirely predictable: phone makers desperate for something to rival iOS, and Google provide it for free. Why would they turn it down? Android's popularity, in a funny sort of way, is actually indicative of the iPhone's lack of serious competition. What would be amazing is if one of the Android handsets outsold the iPhone.
I'd suggest the much more plausible line of logic, along with being logically sound, is that as Android is now outselling the iPhone, the Android is a serious competitor to the iPhone. Pretty much by definition of "serious competitor". Will you still be dismissing it as "not a serious competitor" when Android outsells the iPhone by a factor of two? Because I rather expect it to only be a matter of time.
