"There's a reason that most (90 per cent!) people happily prefer Windows to Mac OS X, and buy Windows machines. They're comfortable with the experience."
You are kidding yourselves.
The main reason is that Macs cost perhaps twice as much as PCs for similar CPU power.
You do get a better experience though, except when the Mac hardware is deemed to slow to get further OS updates, at which time your investment in equipment that generally keeps its value better than PCs, suddenly goes south.
The other reason is that PCs have much more choice as gaming platforms.
