My observation here is that everyone is entitled to their own definition of futility. Personally, I get my kicks chasing around after Tigers with Stuarts, so draw your own conclusions.
As for Apple and gaming, I plead a certain amount of ignorance -- CM is the only game I have either the time or the inclination to play these days, so I'm absolutely not big on the gaming scene. Still, I do know that a couple of game publishers, like MacPlay, seem to get by quite well without Apple's encouragement, so it can be done.
In reality, if I were a truly avid gamer, I'd probably own a game box or a PC, because that's where the action is. (Yes, I'm entirely prepared to concede that the PC is the superior game machine, but I use my Macs primarily for making a living, so once again, draw your own conclusions.)
