i'm probably like in love with this desktop or something mad gay like that.
as long as you don't have more than 5 windows open the multi tasking in gnome 3 is pretty damn quick with the menu hotspot.
honestly i'd pay good money for a tablet as well built as an ipad, running arch linux and gnome 3
maybe i'll contribute a gnome shell theme or two. altho it seems quite.. dead? or just inactive.
