Well, as usual it was not an easy upgrade (given the fact that most of the linux versions have problems on the latest hardware) as I am used running the LTS versions as Linux is my primary dev environment.
As to my surprise, this time the Radeon drivers got upgraded easily and i915 Intel drivers failed. So had to black list the on-board display card and Natty's Unity showed up. I must say I love it.
This cheat sheet is really good to get addicted with Unity.
