I've always said, "If you want to play games..."
[N]ext-generation consoles seem set to surpass the PC as the premier platforms for gaming, which means anyone who’s resisted switching from Windows because of the lack of games for the Mac will have one less reason not to switch. I think there a lot of guys out there who are starting to think they’d be better off with a new Mac and an Xbox/PS3 than with a new Windows PC. Years ago, when I was more fanatical about evangelizing the Mac, whenever the gaming argument came up my reply was always along the lines of "If you want to play games, go buy a Nintendo." (Update the phrase with the console of your choice.)
