Fortunately, it's not as if Microsoft touted Vista as the Windows for Gaming, so we can't really blame them for it sucking so bad for games.
Unless every single dev stops making games for XP, I'm not switching. I fail to see a single benefit in Vista. Ofcourse, MS's monopoly will simply FORCE everyone to switch, yet again.
Well all very amusing but you're basically ignoring driver issues as being the major factor (and with a new driver model this isn't shocking) and the fact the DX10 _will_ see a huge drop in DX overhead for gaming. Time will tell I suppose but i'll not be shocked to see the same game running faster on Vista in DX10 mode next year - or at least with a deal more eye candy (there's always a tradeoff there).
We all have a choice tho and you're right - until there's a tangible benefit for YOU then don't make the switch.
