It's not the same. If you say "Mac or PC", it is understood that you mean "Apple computers, or other type of general-purpose personal computers, i.e., non-Mac PCs". But if we interpret "PC" only as "Windows computer", then there's this huge number of OSes we're not taking into account, since we're just considering OS X and Windows.

I suggest that we're all getting a little too pedantic here. The point is it's basically all the same hardware. You can buy anything and put any OS on it, although it's not so nice to put OS X on hardware that didn't come from Apple.

That's my point: "Mac PCs or non-Mac PCs".

Or simpler: 'Mac, Linux or Windows?'
