My opinion, mac's are okay, I've messed with em and they worked pretty much flawlessly, however every Mac owner I've ever talked to thought their shit came out coated in gold and smelling like a fresh summer rain. That includes relatives, friends, and people who used to call in to the cable company to get support. Their shit can't be the one at fault, if you ask what version if windows they're running (which was 98% of all users who called in) they got pissed, and there is no way their precious Airport can be broken. You got regular jackasses who had windows machines all the time, but atleast they didn't try to act elite. And the only guy who ever called in that had a Linux couldn't connect because he didn't pay his bill and threatened to hack our system.
So cliffsnotes, the ordinary user for each operating system I've dealt with was:
Windows - Dumbass
MAC - Elitist Dumbass
Linux - Imma hack j00 Dumbass
Edit: Now that I'm thinking back, there was one other guy who had a Linux PC who thought it was "Windows Vista XPGT" or something like that and claimed to no end it was Windows based.
