And Apple has about 4-5% of that "growth" market, too... Just like the general PC market. If you want to claim 24% annual growth is flat-line, be my guest!
And remember, for every Mac sold, for every iPhone sold, Microsoft still gets a chunk of change (ActiveSync license, among other things). I wonder what Microsoft licenses from Apple that is in every Microsoft product?
The counter to your statement was that Microsoft doesn't get revenue from all that growth, since it includes OS X and Linux.

I'm sure there's a lot of cross-licensing going on. For example, Apple licensed font technologies to Microsoft. Given that Apple holds something like 400 patents on the iPhone, much of it for the basic touch and multi-touch tech, it's likely Microsoft is licensing Win7 Phone tech from Apple. And don't forget, Apple is hardware too, with all those patents on phone and tablet hardware to collect on.
