As LMDE2 is based on Debian Stable and will not see XFCE 4.12 for a LONG time (2 years.?.) I have decided to upgrade from XFCE 4.10 to Xfce 4.12 using the Mepis MX-14 repo.
Not recommended for production machines.
Make a backup first....
See this post for details.

Not being a Mate fan, and preferrring XFCE over Cinnamon. I just installed the LMDE2 RC (Cinnamon) and added the XFCE desktop on top of it. Very easy for anyone wishing to try. Just install the XFCE4 package from Synaptic (Its a meta package that gives you all the basics).
I also added:
some of the "xfce4-goodies"
(The panel is on autohide at bottom, a setup I prefer)...
