Steve Ballmer: Linux större än MacOS X

I think depending on how you look at it, Apple has probably increased its market share over the last year or so by a point or more. And a point of market share on a number that's about 300 million is interesting. It's an interesting amount of market share, while not necessarily being as dramatic as people would think, but we're very focused in on both Apple as a competitor, and Linux as a competitor.
