Like I said about MeeGo Harmattan. Microsoft would do anything to kill it off in favor of Windows Mobile, and they did by seriously restricting it's availability and Steve (Monkeyboy) Ballmer has made it clear that he's out to kill off open source.
Suggested figures indicate that the N9 outsold Nokia's Windows devices, and probably would have continued to do so if it was shipped in quantity worldwide.
My guess is they're trying to muscle in on something else. But what? some sort of Alien Dalvic type of integration?
