I am with Ubuntu Unity on my laptop and I like it much. I like it more than Gnome3 or KDE because it is more screen efficient. In maximized windows Unity merges the window title bar as well as the menu bar with the unity bar at the top o the screen. That is one bar vs three bars in Gnome 3. Else I think about "all systems" are on right track with the super-button->type routine. Personally I think both Unity and Gnome3 is overdoing this routine when they take all screen space. IMO I think it would have been more elegant if the super-button just made an input line in the top bar for commands, maybe at most one additional bar for output (like last used apps/files and apps/files similar to input).
