Google and Apple's approach are diametrically opposed.
Apple wants complete control of the environment to ensure their vision of a complete user experience.
Google wants to give people choices to find the experience that they want.
Apple will succeed if people, other than their rabid fanboy base, are in fact sheeple.
Guess what, this battle has been fought before, and Gates & Co. won that round. While Apple remained the "premium" brand, the rest of the computer industry bowed to economics and went with more pragmatic solutions.
The real danger to Apple at this point is that the more exposure they get, the more the deficiencies become apparent.
"Mark my words: Google's gonna make it interesting, but Apple's got the innovation, expertise and most important, the experience in software AND hardware to end up on top."
