I find the whole Vista Vs Xp thing amusing.
It seems some folks like to swap over just because Vista is the "latest and greatest" and diss others totally disregarding the other persons needs.
Evidently, computer enthusiasts are a peculiar and sensitive lot. They want the latest OS and computer hardware for no other reason than to stay on top of the technology curve. In there minds, that justifies a need. Computer "stuff" is a hobby for hardcore enthusiasts and some of them are delicate in matters pertaining to their enthusiasms.
Take Vista for example. Everybody knows XP is a robust and mature OS. It's a great OS but in their minds of enthusiasts, new = better and no amount of finely crafted arguments counter to that notion is going to register for them. It's simply a matter of interpretation when determining whether the "features" of a new OS make it a better than the previous version. Apparently, with respect to Vista, there is plenty of room for debate...
I haven't installed Vista on my primary box because I have 2 pieces of relatively expensive software that are not compatible with Vista. I don't wish to replace or expand my existing hardware to achieve the same level of performance that I am experiencing with XP. Additionally, as compelling as DX10 is, there aren't any titles currently available that impress me enough to use that as rationale for making the move to Vista:

I can see how PC enthusiasts might interpret apathy with bashing with respect to Vista. Nevertheless, it's interesting to note Vista users passion and XP users smugness.
