First time I installed Win2k(prof) was an upgrade to the 9x kernel..it went great...but I decided to format and go 1 OS only and have gone that way(with the exception of a 4 month Dual OS system) since.

Hi,
 
I have two systems at home - the first (and my main one) is dual-booted with 98 and Win2k Pro and works perfectly.
 
The second (a rather aging Gateway) was upgraded from 98 without any problems - all hardware was detected and installed correctly and most of the existing software worked fine as well.
 
Overall I have to say I've been EXTREMELY impressed with the stability and performance of Win2k on both systems - sure you get the odd problem with video drivers but that's the chance you take with pre-release betas.
 
Incidentially, I installed the final version of SP1 there yesterday and everything is still working fine....this has to be, in my opinion, Microsoft's best Opsys yet. (and no, I don't work for them!) ;-)

I never upgraded win9x to win2k. always a fresh install.. I did upgrade nt4 though..

... always a clean install ...

Installed w/ dual boot 98/2K and works fine...as what they say...i think its the best os so far if ur not gamer...installed the SP1, so far not any single problem found encountered....

I still have yet to run into a problem with any game on Win2K [Quake3, Unreal Tourney, DiabloII].
 
Incidentally, I installed clean...

I ran a dual boot with 98/2000 for a month or so until I had tried everything under 2000.
 
Once I'd proved to myself that everything would be ifne, I wiped everything and did a clean install.
