I have taken a look at LMDE before, and this version is largely the same. However I decided to try out the XFCE edition of Mint DE.
This is the default desktop. As you can see, it is pretty much the same as the GNOME desktop. For a change I am using the 64-bit version, but both this and the 32-bit version look identical.
The menu actually bears a resemblance to the LXDE version found in MintPPC.
The about window tells us that this is XFCE 4.8.
The file manager is pretty much the same as any other distro.
LMDE also bundles Firefox to do web browsing.
