Then, the question again, what is happening? You want a Linux computer to work with it, not to show the superb desktop to your friends, while crossing your fingers willing that the X server don't crashes again this time, or the system doesn't hang.
I think that Desktop developer companies like ubuntu, fedora, kde or gnome and others are missing the point here, as user experience is very important, but stability is the FIRST BIG part of it, and no the effects, shadows, or where to place the buttons.
