I'm not a Micro$oft advocate but I think XP's stability is greatly dependant on the machine and the drivers in use. I am using XP on a MSI Dual AMD MP motherboard with 2 gigs of ECC DDR and usually only turn it off once or twice a month. (start feeling guilty of the power it's using when I'm not around... LoL)
I have Apache, MySQL, Zone Alarm, Zen Studio, Klient, Outlook (now outlook fails from time to time and restarts), Ulead Photo Impact and Dream Weaver (which fails now and then also) running almost always.
I don't know though. Perhaps I'm just lucky so far.
