Got my invite as well. Going to give it a try. Need to install Ubuntu, I hate unity so much. Nearly as much as Metro. Think ill just can it for MATE and see if Steam runs fine with that.
I actually experienced problems with Unity - buttons in both Steam and Uplink along the bottom 'bar' refused to work. Changing to XFCE (my preferred environment) and that problem went away.
That's interesting, I would have thought the bugs would be seen on non unity interfaces first. Purely because unity is the default gui for ubuntu.
