You just made a lot of assumptions there without anything to back them up. I, for example am running a windows install of windows xp from 2003 repair installed through 4 different computers and finely optimized to my liking, on a Macbook Pro with a 3Ghz processor, 8GB of ram (of course it only uses 3GB) and an ssd Drive ... I have a copy of windows 7 Ultimate that I got at SxSW (Microsoft gave them out at their party) ... I'm a busy person ... I have 60hr workweeks and thats not counting weekends ... losing a week of productivity (because thats pretty much what it would be) upgrading to windows 7 while I back up my data, install windows 7, install all my apps and try to restore the data isn't something I'm going to do anytime soon.
