Gnome seems a bit faster, and the overall look is a bit "shinier".
Unfortunately, I was not among the few who do not experience problems upgrading
. Probably because I have lots of packages installed from the Universe repos, and Ubuntu, Kubuntu and Xubuntu.
I would suggest to anyone upgrading to use Aptitude, and DEFINITELY NOT the upgrade manager. At least aptitude will let you see what it is going to remove, and you can stop it. Upgrade manager just removed stuff without even telling me what it was removing.
