I agree with the University Policy
For those that didn't follow the University link, the school basically says get a Mac to avoid viruses and other malware and cut down on their support load. Bravo! A good policy. My kids have been using Macs in public school for years and while freezes and such were commonplace before OS X, stability is now the norm.
I have been using Mac for several years now but only recently converted all of my household machines to mac. Until this past February, it was a constant litany of "I can't print" alternating with "I can't get on the net" and the occasional virus, adware or spyware. I find I am able to get more done on my Mac at home than on my IT administered machine at work. The difference? Virus software. Every document I open on the PC requires a virus scan. At 25-50 documents a day, it really gets in my way. Yes, there are some annoynances on the Mac. I'd really like it if Time Machine could sense I was typing and go away and come back later to do its backups. There are a few other annoyances as well, but they pale by comparison to the hassles on windows.
Mac really is better. Really. Is it M$ fault? In part, yes because of their legacy of ignoring security. In part no, because they aren't to blame for the plethora of adware/spyware that requires such aggressive antivirus software.
