I've used Win2k already, and I don't really like or dislike it that much. If you're running a server, then of course, Win2k is definitely better than Win9x. As for stability, I'd have to run it at home - I only used it for a few weeks in my OS class at college. It did lock up on me a few times though, once during the install, and twice while it was up and running. It does take a bit of getting used to, but it doesn't seem all that bad. If Win98 does the job, keep it. I personally like 98SE; just waiting for Linux to improve a bit more before moving to it. Plus, a DirectX emulator for linux would REALLY be nice too...
