Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W610 nor Olympus Stylus XZ-10 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus XZ-10's 3.00" LCD screen is slightly larger than Sony W610's 2.7" screen.
