That's a surprisingly high percentage, elias! Obviously Java game audience is not "average"...
Luckily, no one needs to reboot for your games since they always come in all varieties.
This bootcamp sub-thread is off-topicky, but still:
My Intel iMac is the most powerful HW in the house now. Ever since I got it I wanted to find something to benchmark/showcase its graphics and processing power. What's better than a game, right? But there was NOTHING available for Intel (I know Apple took everybody by surprise in January). I tried a few PPC game demos, but their performance sucks, especially if you want nice graphics.
Then Doom 3 got a Universal update, but I didn't feel like shooting zombies in dark corridors. Call of Duty 2 should be coming in May, that's a looong wait. Now Quake 4 was released - still too close to Doom for me, but I tried to research and get it.
Compared to the Windows version it costs 50+ % more, and even though I still wanted it, I couldn't get it locally. I know I could mail order, but I'm an "impulse buyer".
Then I found that the Win version already has a multi-core patch out, which dramatically improves performance, also there's an SDK for mods... it may be coming "later" for Mac, but I just grabbed the Win version now. So wow, now I can see how my Mac shines - in Windows
Now I feel bad about my "impulse" decision, perhaps I should have supported my camp? Their position is pretty bad since they have to deal with PPC code as well as Intel, which will never be as optimized as Windows. I don't think they can justify that effort for a limited market.
I promise I'll get a "real" Mac game one day...
