I used a pc for 6 years and still do, and was in denial everytime someone mentioned a mac, until I actually used one..

then it was like wow...

I developed video games, if that isn't cause enough to show I was hardcore pc (mainly because mac games suck, and are finally evolving into something playable) then i dont know what is...

and the reason most software is developed for a pc is because windows has saturated the crap out of the OS market...

The point is, I haven't had to uninstall any program because it didn't work properly on a mac, something that happened frequently on a pc.
