Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic L1 and Leica Digilux 3 have exactly the same weight of 606g.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Panasonic L1 and Leica Digilux 3 have the same Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-L1 nor Leica Digilux 3 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic L1 and Leica Digilux 3's LCD screens have the same diagonal size of 2.50 inches.
