It is a feature, interfaces between pieces of software is some of the most expensive and challenging parts of writing it. When every piece of software is written specifically with that interfacing in mind it will just run better. Now Apple hardware is starting to do the same thing?

I am pretty bullish on Apple right now and could easily see a future where Windows isn't even used for gaming anymore. When Macbook Airs start to be capable of running high end games what is the point of getting a huge Desktop running Windows jammed with bloatware from 100 different companies?
