Apple fights this phantom battle with one hand tied behind its back. It does not farm its OS out to the world. Imagine if, tomorrow, Apple said to all hardware producers, you can have iOS. Android's market share would plummet. And no tech geek can tell me otherwise. Put Microsoft on Research in Motion ( RIMM)-watch. The only thing that keeps me from saying the same about Google is that, in many ways, the company does beat to its own drummer. It dominates search and does a nice job diversifying what is, for all intents and purposes, its sole revenue stream -- advertising. That said, when Apple stumbles, as it did with "MappleGate," and when it falls, don't blame Google or Microsoft. It will not have been either company's fault.
