Microsoft didn't have to worry in the past about the Linux desktop because it was too much work to get set up and maintain. That has changed. I don't think the Linux desktop experience is quite there yet, but it is getting really close. In some ways it is already much better than Windows, and where it is not, it is catching up. What Microsoft fears is that at some point Ubuntu and > usage will reach a critical mass and explode on to the desktop scene. For this to hurt Microsoft, it doesn't mean Linux has to put them out of the market place. If Linux gained only 20% of the desktop market share, it would hurt, and probably hurt their pride the most. It may not happen, but Microsoft would have to be stupid to ignore the possibility. And quite frankly, I really don't know what Microsoft can do to stop it. They will try of course, and even resort to some of the dirty tricks they used in the past. But FOSS has no center to aim at. It's apparent weakness is its strength. It's a bunch of smart people all over the world doing what they like to do. I don't hate Microsoft and I don't want them to go out of business, but this is going to be fun to watch. I am hoping for the success of Linux on the desktop. This will be good even for the most dedicated MS or Apple fanboy. Real competition in the marketplace is good for everyone concerned. It will make whatever you choose to use better.
