I worked as computer support in a place with roughly 60PC/40MAC split. Macs were running OS X 10.2, and PCs were running XP when applicable, about 75-80%. Y'know what? With 3 dedicated PC techs and 2 mac techs, you want to know what the service que was like? 60-80 for the PCs, and 10-20 for the macs.

My mac has been far more reliable than any PC I've known.

Meh... this is getting into a flame war, and will not end... I'm out.
