MacOsX is not owned by Microsoft. These two companies have a 5 year agreement , never heard of MAc BU? They differ so much, they're almost killing each other. Apple is more interested in hardware selling, which leaves no bucks for mighty mister softee. Microsoft has a small team of developers implementing stuff like "office v.X" and media player. And Yellow DogApple is been around for a while now. I think that having the option is not a bad thing at all. I personally like having all my web developers power application and heavy-load graphical designing out of windows and Bsd is not a solution for me. Mac has made it possible.
