I would agree. Win2K is much more stable than Win9X or even Win NT 4. Also Win2K supports modern devices like USB and Firewire. The only thing I like better about XP (on my new laptop) is the independence between screen resolution and onscreen size of fonts, toolbars, icons, etc.
I run XPp on the desktop and it does very well. Occasionally it stumbles but recovers very well. It has only come to a screeching halt one time when I was pushing it to the limit multitasking.
