Newer here, I've discovered XFCE with xubuntu. A friend of mine wanted to remove windows on his ultrabook, he ask me for a linux. After having tested a lot of live cd, my choice was to xubuntu for him, he enjoy it.
For me, I haved my pc to reinstall. My choice was quick, exit Gnome 3, and welcome xfce. It runs on debian sid.
Sometime is good to change
