I can't BEGIN to tell you the number of problems I've seen with Vista as a computer tech. That OS is a piece of trash. It's a freakin' memory and processor hog for what it does and it's security features are WAY too intrusive.
XP runs faster, handles software issues better, and is a hell of a lot easier to work on/with.
I don't know what Micro$oft was thinking when they coded that piece of crap.
Unlike Windows ME, it not only crashes, but has so many security features that it ANNOYS you as well !
Then there's the issue of DRIVER SUPPORT. When XP came out, drivers for stuff were there in pretty short order. I don't see the same thing going on with Vista. It seems a LOT of software companies are really digging in their heels and the new Vista drivers for older stuff is few and far between. Unless EVERYTHING you have is brand spanking new (and even that's no garuntee), you have a high probibility of having driver problems with Vista somehow, somewhere.
