I agree.
I have a multi-boot 64 bit machine that runs (amongst others) Vista, SuSE and Kubuntu (all 64 bit).
I have to tell you, Vista is by far the worst performer of those three and if I had to choose an overall winner, Kubuntu just eases out SuSE by the narrowest of margins. In truth, Kubuntu's just a personal preference rather than anything solid when comparing with SuSE.
Admittedly I only have Vista RC1, but to my mind, it's nowhere near prime time.
Interestingly, those that I've spoken to that intend to go and buy Vista, are all opting for the 32 bit system to run on their 64 bit machines. What's the point of that? Other than perhaps, the availability of drivers for the 32 bit system!
