I'm not sure.
I use one because i don't like wrestling with a beige box trying to make it ssubmit to my will.
( I learned on MS Dos machines, switched to Macs about 14 years ago and have never looked back)
I think a lot of peoplee get up-tight because of the slogan "Think Different", and because a lot of graphics peoplee aand aanimators do use them.
(If you're an artist, you gotta be eeither gay or a commie or both, right? LOL!)
I don't think any of the major universities use Macs anymore..
I know I was dissapointed when they wer taken out of my daughter's new school.
I think a lot of the anti-Mac prejudice is simple elitism: Mac users are too dumb, Mac users are dilletantes, etc. And old-style iMacs came in jewel-like colors, so they look funny and like a toy and therefore can't be a REAL computer.
No, some of us just don't want the hassle and heart-ache of using Windows.
We know what we want the machine to do, we don't want to be constantly maintaining it it, and we want it to perform NOW.
