"It is possible to install a GNOME 3 shell (version 184.108.40.206 at present) from the Ubuntu Software Centre, but if you don't like Unity, GNOME 3 may also not appeal, as you cannot even scale the size of its icons (or at least not without editing the gnome-shell.css file)."
Ubuntu have killed off the spark for all the GNOME lovers out there. But fear not! For there is now a new official flavour of Ubuntu in development made especially for GNOME!
It is called GNOME remix! Can't wait!
