I mostly agree, especially your last sentence. With the exception of our Exchange/AD environment at work (which everyone uses Macs on top of) I only boot Windows when some piece of software I can't get around requires it. I've used a combination of OS X and various Linux flavors to do everything for a few years now and haven't missed MS one bit.
My father on the other hand (who told me I was nuts back in the 90's when I explained how Linux/OSS would change everything) still clings to Windows even though it's a major source of frustration for my folks. I would even raise the age you posited, as I am in my early 30's (though it could just be that I'm immature).
I disagree with your assertion that the war for mobile is won, however. I think MS is down, but certainly not out. If the last 10 years are any indication, things can turn around in the blink of an eye.
