I use 2gb. I was on 1 for a while and had my swap on another partition, but even bare minimum apps take up room. I tried 1.5 but that didn't work either. I'm up to 2 now. Everytime I resize I use partition magic. With the older ver of Magic, it would screw up my boot stuff, so I'd have to run the win2k cd and recover, but I wouldn't lose any info. Now Magic supports win2k and it's all good!

ps: well, after running the whole year on this install of wi2k, i'll be reformatting and reinstalling. 6months w/o reinstall is really good compared to win9x which was nearly every month.
