MACINTOSH = Most Applications Crash, If Not, The Operating System Hangs.
Ok, all joking aside, to me the biggest problems with Macs are their price. I just can't justify spending $1500+ on a home computer when I can get a Dell for $500. I mean really, I could get one PC computer for everyone in my family for a little more than the price of 1 Mac.
But, a BIG (and I mean big) plus is that it's not going to run windows. I've got three computers at home now, one running WinXP Home and the other 2 are Linux / Unix boxen. My windows box is a POS. Crashes about every 3 days, and constantly needs to be rebooted. Although, it may be partly my fault, I actually install the "security updates" from microsoft and everytime I do, the system gets more and more hosed.
Funny, I run a security update on my Mandrake box (which doubles as my mail, web, file and print server) restart some services and I'm done. In fact, I just checked my uptime:
Not bad - 101 days!
08:07:07 up 101 days, 18:14, 2 users, load average: 0.08, 0.02, 0.01
Where was I, oh yeah Macs. Another benefits that Macs have over PCs is their system architecture, which is more stable than a PCs architecture. They also have fantastic graphic rendering capabilities.
