You do know OSX can die over time? Some of our mac pros at work near enough grind to a halt after a while.
Another smug Mac user here... Re-formatting? I honestly have no idea what you're talking about.
I do however hate people who call their computer their "rig".
You have to treat OSX horrendously for ages to slow it down properly, I've only seen machines really want a reformat once and we really abused them for a good while to get them to that point. Mine had 1500 Helveticas on it. Never had to do it on a home machine though.
