I believe the biggest reason android adoption is so high is the availability of android devices on all major US carriers as opposed to the iPhone being an AT&T exclusive.
Up until this point at least, I think you're correct. I certainly would have liked to have purchased an iPhone since long before Android was ever released, but AT&T's reception in my area is abysmal.
However, even if Apple can get out of their exclusive arrangement with AT&T, it may be too little too late.
