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 Fujifilm X10 nor Canon PowerShot SD4500 IS / Digital IXUS 1000 HS / IXY 50S provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon SD4500 IS's 3.00" LCD screen is slightly larger than Fujifilm X10's 2.8 screen.
