marginalization of windows

I'm currently "watching" gizmodo's liveblog coverage of apple's WWDC 2009.  With all the everyday-focused enhancements (mail/jpg/pdf opening speed improvements, find my iphone, etc) it's obvious that apple computers really are computers for the average person, and windows machines are oddly enough for specialized interests.  That's what fascinates me- that Windows is now becoming marginalized as something used by the business or gamer subcultures alone.
