A quick search of Apple's website turned up 1444 game titles available for the Mac.
Granted, they may not include the latest and greatest PC shootemup, but 'no games' doesn't quite wash.
OK, "no games" is an exageration, but none of my kids has ever wanted to use my Mac for anything. On the other hand, they were always whining to use my wife's PC, back in the days she used one, so they could play an important game of Doom or some such nonsense while she was trying to use it to earn money.
And, they all had their very own computers, but somehow if you load enough games on a PC it stops working. The only surefire way to get it up and running again is to re-install Windows, which wipes out all of their vital saved games, so they hate that like sin.
