“Being able to install GNOME Shell in Ubuntu Oneiric is
exciting. And as we experienced in our earlier review of GNOME
Shell in Ubuntu 11.10, GNOME Shell has came a long since its first
release and now is a very stable, fast and usable shell for GNOME.
To further improve the functionality, GNOME Shell has extensions
support. Though these are very early stages, there are quite a
number of really good GNOME Shell extensions already.”
