Alright, I'm sorry but first off: drivers do not disappear. They don't get up and walk away. Some other factor causes them to disappear, and blaming it on Vista is like complaining that your car has mud on it after driving through a swap. As for the nVidia 8000 series drivers, uh, lol, they have had drivers for those cards for freaking ever. And drivers are not Windows problem, drivers are 3rd party provided software.
Either way, Win7 looks interesting, and that "peek" feature actually looks a lot like what I was telling my friend Alt-Tab should have(on the Mac). If this machine had it(Alu Mac)I'd love it, I hate a cluttered taskbar more than anything. Its really looking like they have learned from the mistakes they made with Vista, and anyone who says the "peek" feature is useless pretty should really step back and hit up Expose, new useful/pretty features are often considered useless by the opposition.
