The think its nonsense to have to say we need a standardized desktop top to compete with Windows. Choose a distro, the poorly configure desktop distro will disappear and the better ones will grow, it's called evolution. Eventually, there will be three or four big distro chooses. I think we are getting close. And when we do, you'll see migration into the cooperate desktop environment.
People use Windows because it's what they use at work. When companies move toward linux for the desktop the users will start buying Linux machines for home. Cooperate environments aren't going to give their users a choice between GNONE, KDE, etc. They going to choose a distro, perhaps customize it a little and give the user one desktop environment, one email client, one office package, one xxxapp. Then average users going to go home a purchase the same distro for home.
History repeats itself!
