Why the hell did you not test gnome-shell its now completly useless for me and surely 50% of the linux users that use linux as desktop system. Unity is as far as I know, only used under ubuntu, and maybe less ubuntu users use gnome-shell than unity but on other distries 10 times more users use gnome (shell) than unity so if you test kde against unity why not gnome.

Because Ubuntu goes a few years a retarded solo.
