My experiences in both OSX and Debian Linux are equivalent on the rate of failure to success. (For me really any Linux variant)
Sure, it took me a while to stop suckling on the command-line teat, but I did do it. But that was a while ago... and the fond memories have faded to a general warm-feeling inside.
It is actually a toss up as to wether or not Windows will work after an installation of said game, or of said Spyware, Adware, OS updates... anything, it all depends on the moon phases and what the tea leaves look like. For those with a sacrifical bent, how many fertile chickens you slaughter and drain the blood from and burn in the fire.
Linux and MAC OSX both have a very robust set of features that can be turned off and on when and how you like. You are just more familiar with MAC by choice, Windows because of the 92% number.
I am more familiar with Linux in General (love that Debian Sid) than I am with MAC OSX, but there again I know Windows because of that 92% number.
So, in effect you are telling me, the reason I don't like MAC OSX is because I don't understand it... I am telling you you don't like Linux because you don't understand it.
Sure, I love Linux as much as you Love OSX, effectively we are both zealots... just to different beholdings.
