I am not a supporter of MS but calling for its death is a bit too much for my taste.
I consider the fragmentation of Linux worse than the monopoly of Windows, from a gamer and business point of view. Of course with monopoly there are other problems too.
What I do NOT want is a return to the 80s where we had like 10 OSs, usualy one per computer, MS-DOS, TOS, AmigaOS, etc etc.
I also disagree that Windows is not a "real" OS. If it isn't, it sure fakes it very well.
