I've got to disagree, I installed Vista Home Basic on a P4 2.0ghz with 512MB and integrated graphics. It didn't look as nice, and you could only run basic programs, but it was still functional enough to use. But yea, some things in Vista are pointless on such machines, Vista was a future/forward looking OS in many regards. And machines powerful enough to get the most out of Vista have been in the $500-$600 range for probably about 2 and a half years now.
