I recently saw a freshly installed AMD64 ~3GHz system. Yes, it booted very fast (no doubt thanks to the SATA drive and 2 GB ram), but there were still delays of *seconds* in some interface interactions. That's just not acceptable to me at all. My own 1,6GHz system (2000+) is still ridiculously slow at most standard operations. It's all brand stuff too (decent Asus board, Asus Radeon, fast ram etc). I can agree that Windows isn't as bad/slow/unstable as some make it out to be, but it's still far from something I could use on a daily basis without tearing my hair out. It would drive me nuts if I had to wait for it to respond. I guess that's why I have shortcuts to the two games I use the machine to play right on the desktop. :-P
Some parts of Windows respond well enough assuming nothing else is running on the system, but what use is that, when you use an operating system for running programs? Regardless it's just not fast enough. As for Windows ruling... well, for games it's certainly > MacOS X, but for pretty much everything your average user needs to do MacOS X > Windows. By a friggin' huge margin.
I still like my OS4 better though 8-)
