Running Ubuntu 12.04 Precise Pangolin release finally.. I tried out the Beta early, because I had 10.04 and nothing on my work laptop MSI GT683 machine worked with it. Now everything is working except the fancy lights, turbo, and eco modes.
Still getting used to Unity, I don't like how it combines running apps with an app toolbar - it's difficult to tell what is open or not by looking at it. I think I prefer the older Gnome 2 interface, maybe because it's just simpler and what I know. I did try MATE on LinuxMint12, although neat, it was incomplete and buggy. I found LinuxMint 12's default interface even more odd than unity, like a couple mismatched interfaces thrown together - I didn't get it.
I suppose I'll stick it out with Unity a bit longer.
