I have a win2k license and it's running my firewall/gateway. I haven't put it on my gaming rig because "infinately more stable" just doesn't apply here. My computer simply doesn't hang often enough to be an issue, and I'm not sure everything I have and use will run under win2k, while I'm positive it works under win98.
Saitek X36 USB plus second analog stick/rudders work under win2k? Or are those problems only with XP? And security... I found out yesterday that even though I THOUGHT I'd disabled all servers on my win2k box, it's running a friggen MOTD, date/time, chargen, and a few other services.
I simply can't come up with any reasons to run anything other than win98 other than increasing stability from 99% to 99.5% (my win2k box has hung before, bad network drivers I think), and because some shortsighted companies are no longer creating win98 drivers.
Meanwhile, wineX and the other linux gaming efforts are creeping up on full directX emulation and some openGL games even run a bit faster under Linux...
I'm not sure what Nvidia's game is. Maybe Micro$oft is pressuring them into pushing winXP/2K. If so, they're simply positioning themselves as a vendor that doesn't offer hardware I can use. Pity, they make fast chips.
