I could not have said that better: I actually love the keyboard oriented approach of Unity. If you further install Unity Tweak Tool / Ubuntu Tweak, you can also get keyboard shortcuts for tiling and organizing your application windows. I used to be a Gnome Shell user, but Unity has definitely convinced me in its last version and I feel more productive than ever, as I rarely have to touch my mouse when coding.

If only there was a decent launcher on Linux, I could definitely put OSX behind me.
