Personally, I have been to Win2K and back more than once. Each time I try it cause everyone says games run just as good on Win2K but fact is they do not. Games run better in Win98, no ifs, ands, or buts.
If you turn off your system everyday, then the advantages of Win2K diminish even more.
And those that say Win2K doesn't crash are lying. I've crashed in Win2k many times and that is a big reason why I don't use it anymore, not to mention the compatibility issues w/ certain programs I have.
If my computer is going to crash running Win2k, it may as well crash under Win98 and that is why I went back to it.
You need to decided exactly what you use your computer for and if it includes any gaming, you better off in Win98 and at the very least, a dual boot system because Win2k is certainly not the answer to all problems that everyone is looking for.
