Apple and Samsung had a combined Profit Share of 104% last quarter.... They have this impossible seeming share because most (read: not all) competitors are either making very little profit by comparison or are taking losses. In the case of LG, HTC, and Motorola, some of Samsung's "major" Android competitors, they're all skating on thin ice or have been taking losses for some time.
There is a reason Apple stopped focusing on Android in general when it comes to their Patent Litigation, and the same goes for Samsung.... They're focusing on each other and not the rest of the Android community. If it were Apple vs. Android in terms of Profit Share (Market Share is worth nothing if your Profit Share is shit), then Apple is winning.... If it were Apple vs. Samsung.... Then the battle is very close, and it is hard to determine a clear victor... and as a consumer and a software dev, I don't want there to be a clear winner. Competition is a GOOD thing. When will you jack-holes get that through your heads? Seriously. Android is all the better now BECAUSE of Apple, and the reverse is also true (iOS is better because competing with Android has forced it to be).
The problem with RIM was that their entire business was tied up in Mobile Devices. They were the "King of the Market" (meaning they had no real competition and could basically decide the market's direction at will) for a LONG time. Then, as if overnight, they weren't and they didn't know how do deal with that. They made a lot of bad moves. Apple has yet to go anywhere near that path. They know they aren't the "King of the Market", though they might like to be. The same goes for Samsung and Google... They know Android isn't the "King of the Market", but they want it to be. This is a good thing, as it forces both groups to innovate new software and hardware features.
