I have just installed Linux Mint Debian Edition (LMDE) which is a rolling distribution based on Debian Testing.
Here are the screenshots of the installation process.
The installation procedure is really easy, it comes with full support for Office production, with Open Office installed. Rhythmbox, mplayer, vlc, brasero, and others in the sound and video category. F-Spot, Gimp, and Simple Scan in the Graphics category.
/etc/apt/sources.list is as follows:
deb http://packages.linuxmint.com/ debian main upstream import deb http://ftp.debian.org/debian testing main contrib non-free deb http://security.debian.org/ testing/updates main contrib non-free deb http://www.debian-multimedia.org testing main non-free
I really like it, I have never tried before Linux Mint, as even though I like Ubuntu, it is not really my fav Distro, but Debian is a different beast for me, I really like it.
So, I will be using this LMDE, and letting you know my experiences.
It is a rolling release, well it is based on debian squeeze, but as you have seen in the repositories it is marked as testing, so as soon, as a new testing appears, you will automatically have the new software. So to stay up to date, just run
sudo aptitude update && sudo aptitude full-upgrade
Edit: According to Omns it is not a good idea, to issue the above command. Read comment below.
And you are done, I have been using Debian Squeeze, together with Arch for more than a year, and Debian is really stable, the testing name is what it appears to mean.
