It's debian with a pretty face and 'new' packages. Debian itself is great but a little too far behind the ball for me.
It defaults to a gnome wm, but I've swapped that out and have been running good old fvwm.
The default install starts up a bunch of unecessary services, but it's not hard to pare everything down to only those bits that you need/want.
Give it a shot!
