Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic S2 is significantly lighter (66g ) than the Panasonic FH20 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-S2 nor Panasonic Lumix DMC-FH20 (Lumix DMC-FS30) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
