Well I will say, I agree with Kakaze, as I mentioned before I suspect the reason some games perform better under WINE and Cedega has as much to do with the overhead that is NOT there from not running windows as anything.
Unfortunatly my concern is that people like EA(Ok if only they did it I wouldn't really care

will see this and think, oh well we ONLY have to write for windows now as then those other platofrms can just run it under emulation, why should we waste resources on this?
Oh well, at least with Vista here, Mac OS does start to look better for gaming from all the crap you are not competing with for system resources, even if the Mac is a bit worse than most linux setups even for that...
Speaking of which remind me to post a screenshot of my mac when I am done, on my workstation at the moment, but e17+shapeshifter amkes my mac at least look beautiful and run my software well and still maintain total hardware support.
I love the BSD subsystem in Mac if nothing else

I will drag it kicking and screaming out from under Apple's shadow and twist the Mac into something I enjoy looking at
