I agree totally.
I look after around 200 pc's at work; about 60% Win 2k, 20% XP and 20% Win98 (yes 98, i can hear you laughing you know...). I get most problems with XP users with programs crashing and general slowness of the machines. The Win 98 machines are...well, need i say more....and the Win 2k machines are rock solid.
There's too much fanciness with XP and especially with the introduction of Vista, for use in business, even with all visual settings turned down.
The majority of business workers don't need all the extras; as long as they can get their mails and do whatever it is they do, who needs fancy looking transparent windows and pretty buttons?
