Since it is tax time once again, I found an interesting article from the Software Freedom Law Center about Microsoft and the Patent tax. Whilst this definitely gives a one-sided view of that matter, I am curious as to what patent infringements Linux has done according to Microsoft's Steve Ballmer. I am hoping that Mr. Ballmer will enlighten us with more details instead of creating fear, uncertainty and doubt (FUD).

So, in addition to the patent tax, marketing expenses and profits, how much does a Microsoft product really cost?
