Wait. Did you spend $2000 on a PC, or on a Mac?
Like I said earlier, everyone has different experiences. As surprising as it is for some people to believe, there are people out there who have had nothing but trouble out of their Macs, and think OSX is crap because of it. Same goes the other way around (as it seems to be your case). Sometimes you're just unlucky.
But generally speaking, crashes on both OSX and Windows are due to hardware faults 99.5% of the time. It takes an inordinate amount of bad coding to crash an MS OS post-Vista, almost to the point where someone would have to do it on purpose to get it to happen.
Like I had a game crash my graphics card here a few months ago. Back in the day, this would've been a catastrophic failure that'd take the whole OS down with it. All it did was give me a blank screen for a second or two, then send me back to the desktop with a pop-up warning saying Windows recovered from a serious error.
Everything went on normally after that. Didn't have to reboot just to make sure everything ran smoothly or anything like that.
OSX and Windows are about equally stable these days.
