I've been using Win2K pretty much since it came out, and I'm perfectly happy with it. Win98 wasn't bad, but 2K is a lot more stable. I just installed the latest DirectX on my system, and realized that I haven't had to reboot in... weeks. It just keeps running.
I keep an old IBM Aptiva in the closet for my retro gaming fix. I rescued it off the trash heap. It has (I think) a P300 and 64 meg of RAM and an 8 gig HD, but it runs Win98 and those old games quite happily.
I'm sprawled across the davenport of despair.
It's the land of the brave, and the home of the free, where the less you know the better off you'll be.
