Hmm well in 2002 I had a Pentium 4 2.0Ghz with 1 Gig of DDR 266 memory and a Geforce 4 ti4200 128mb card. I remember when I built my system, 2.4 and 2.6Ghz CPU's were out as well but I didnt want to spend the $$ on them.
Honestly, the above computer would have absolutely no problem running vista. I've also got vista running on a PIII 550, 40gig drive, 768mb ram and a radeon 7500 video card and its actually not bad. The box is a compaq and it initially didnt come with that video card. I think the original was some kind of matrox card so I dont know if that would have worked but vista on a PIII 550 is pretty impressive. I'd have to say it was not that much slower than XP. Due to the fact that the radeon 7500 is not very strong, some advanced video options are disabled but it all still works great.

While people were uneasy to try out Mac OS X, Apple did a much better job hardware compatibility wise. Older Mac hardware runs Tiger just fine.
To give you one example, I am running Tiger on a PM933 which was purchased in 2002. It still boots into Mac OS 9 (not Classic) and will run Tiger just fine.
I have not upgraded the Video card or CPU.
Now how many PCs built in 2002 (5 years ago) can run Vista without significant upgrading?
In other words, if I was still running Mac OS 9 and wanted to try out Tiger, I could purchase Tiger for less than $100 and try it out. If I don't like it, I am only out less than $100.
Only HD failures!
