Let's see, the upgrade of the 90+% marketshare OS requires vastly more hardware power, and completely new hardware to run DRMd HD*, that people will have to spend a lot more just to run it. I thought the technology spending boost was just common sense. The more Vista hogs, the more people will have to buy.
BTW, research recently showed the memory "sweet spot" for Vista is about 4 GB.
* Well, you hope, since most "HD Ready" products out there don't really support the DRM.
Not if they weren't even buying Vista to begin with, duh!
