Those keybindings look awesome and make me want to upgrade. Guess I will try it out in a VM first though.

I only had to install the guest extensions to get 3D acceleration and Unity to work.
To do this, open Synaptic, go to Settings -> Repositories, and in the Other Software tab click Add and paste this line:
ppa:canonical-dx-team/une
Save your changes, then click the Reload button in Synaptic. When the new package lists are loaded, install the package called Unity. When you log out, you should be able to choose "Ubuntu Unity Netbook Edition" from the menu on the login screen.
