Microsoft has a majority market share in the new desktop PC marketplace. This is a bug, which Ubuntu is designed to fix, so do I by preaching about Linux to my school m8s and teachers. I got my two mates converting, but one's father has been especially badly brainwashed by M$ into believing that Linux is dangerous, costly and that he is gay. This situation is making my m8's conversion really hard.
However me and him managed to get a teacher very interested in Ubuntu and Mac OS X because she was very pissed off with vista (and all versions of Windows released after 98)

I think The biggest bug out there is Vista.

Hitler would have been proud of M$, after all they have the world domination and have managed to keep minorities below 8% last year.
