There was no Ubuntu with GNOME 3!!!! .It's unity only .Ubuntu 10.10 (I remember it since it was the last version of shipit.
) had GNOME 2.32 and Ubuntu Netbook had unity .
The control buttons on left was on 10.04
The first GNOME 3 nix were either Fedora 15 or Opensuse (cant remember but I had alpha/broken versions of both !!!! )
LM12 is heavily modified GNOME 3 .You can enjoy stock GNOME 3 or MGSE on top of GNOME 3 for the earlier functionality .
