Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 7010 is significantly lighter (48g ) than the Panasonic 3D1 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-3D1 nor Olympus Stylus 7010 (mju 7010) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic 3D1's 3.50" LCD screen is slightly larger than Olympus 7010's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
