Just adopted ( september 2012) LMDE-XFCE, after years on Ubuntu.
Love the following points :
- Semi-rolling aspect (allowing to get Debian-testing with improved stability/reliability at the cost of a small delay in deployment
- Debian base (dpkg/apr rocks)
- XFCE (light, simple)
Dislikes : number of orphan packages
Would love to see :
Choice between XFCE and Razor-QT (as soon as this last one is mature enough) as I'm an avid user of a lot of KDE apps (especially Digikam)
