What matters in the end is personal preference. I actually don't give a shit if some guy gets a few extra fps in quake. As long as I prefer using a Mac, that's what I'll use. If you haven't used a recent version of both PC and Macs, or even NEVER owned or extensively used both platforms, then IMHO you're in no position to objectively comment. People are naturally defensive about their choices - if their choices are attacked, so are they by extension.
Who cares anyway? Arguing about PCs vs Macs is like arguing religion. Neither side will admit defeat (and even usually even refuse to coexist). I'll continue to use both my PC and my Mac and the rest of ya can do whatever the hell you like too
