Huh... I ran Windows 2000 on my PowerBook G4 1.5GHz several years ago with VPC 6, and I found the speed to be perfectly adequate. Sort of like low-end Pentium II performance. I would imagine 2000 was simply faster than XP - and Win7, forget it, too much graphical pizzazz there. I even had MS Visual Web Developer 2005 Express on there, and it was usable!
As for VPC not being faster on a dual G5... sure, VPC itself won't use the second CPU, but other programs and the OS can, leaving 100% of one CPU available for VPC. Otherwise, VPC and everything else would have to fight for CPU time!
