Mac OS X is perferct in everything, but when it comes to video games; vista has the advantage. Why do you think OS X is not performing well against vista in running video games? Note: Do not ever think that Pc games producers will neglect their market shares that they gain from Pc users. There are many games that released on pc exclusively. Actually I wish that OS X can run games smoothly as vista do now, so I do not have to run vista through bootcamp; like many others.
