Buying Vista now would be kind of stupid in my opinion. I had the RTM version on my PC and it was buggy as hell. Not mention (if anyone has paid attention to the benchmarks) there's NO real performance advantage at this time! We wont really know the OS's potential for about 18-months when some real DX10 designed games hit the market. Just like all of the other FLAWED MS OS releases their going to have to put some service packs in circulation before this OS is worth the ridiuculus $200.00 price tag. My PC AMD 4800+ / eVGA 8800GTS / 2-GB DDR / Abit SLi Mobo / is more than powerful enough to handle any of the games coming out for at least (realistically) another 2-years so I'm not in any rush for MS's new over priced crap!
