Weather Sealing
Unfortunately neither the Olympus Stylus XZ-10 nor Canon PowerShot SD3500 IS / IXUS 210 / IXY 10S 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
Canon SD3500 IS's 3.50" LCD screen is slightly larger than Olympus XZ-10's 3" screen.
