Underdog! Underdog!

Speed of lightning, roar of thunder
Fighting all who rob or plunder
Underdog. Underdog!

Anyone remember the saturday morning cartoon from a couple of decades ago? Underdog, underdog.
I was reminded of that cartoon today when I read this article that M$ is restricting their Windows Vista user licenses for people running Windows Vista under virtualization. What is that you ask? Parallels, and others, allow a Mac user to run OSX and Windows on the same machine at the same time. Very handy. You now only need to buy one machine to run both.
Well, this is a direct attack at Mac users who run Windows OS on their Macs using programs like Parallels. M$ is restricting use of their OS software to their most expensive versions, meaning it will cost a user approx. $400 to run Vista on a Mac running under Parallels instead of the cheaper 'home' version for about $100-200. There is no technical reason for this. It is purely financial and shows us yet again the atitude that the Big M has.
Kind of funny to me that M$ is so worried about virtualization on a computer system that only has a 2.7% worldwide market share. Hmm, underdog indeed.
