Here's a cool article by Robert X. Cringely. He wrote Accidental Empires and I think he was a Stanford professor.

This article has several interesting points:

1. Microsoft Windows viruses. Why doesn't Microshit fix security holes? Why don't IT departments apply updates once they are available? The update to fix this latest virus was out a month ago. And someone made suggestions to MS 12 YEARS AGO that would have prevented this virus, but they didn't listen.

2. He argues that Macs aren't popular in business because "Macs reduce IT head count while Linux probably increases IT head count, simple as that." If an IT department recommended Macs, they would be out of jobs. Mac OS X is as powerful as UNIX, but it's a breeze to setup and use.

3. Nerd ego. Nerds like to feel powerful, like they are badass because they can use a command line and setup a Unix machine. Well fuck that. I can setup an XServe in minutes and spend my time doing IMPORTANT THINGS. It's like people who code HTML by hand. I don't get it. It's a waste of time. I'd rather let a program make the HTML and I'll spend my time on CONTENT.

4. Macs cost more than PCs. But the Total Cost of Ownership is LESS. If you factor in all the additional goodies you get, the less support you will need, how long they last, and their rediculous resale value, you will spend less on a Mac than you would on a PC. I know I have
