Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 7000 is significantly lighter (77g ) than the Samsung HZ15W which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Samsung HZ15W (WB550) nor Olympus Stylus 7000 (mju 7000) 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
Samsung HZ15W and Olympus 7000's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
