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 Canon PowerShot ELPH 330 HS (IXUS 255 HS) nor Canon PowerShot SX240 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
