Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A1100 IS is significantly lighter (450g ) than the Canon SX40 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot A1100 IS nor Canon PowerShot SX40 HS 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 SX40 HS's 2.70" LCD screen is slightly larger than Canon A1100 IS's 2.5" screen.
Moreover, Canon SX40 HS sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Canon A1100 IS has a fixed type screen which provides almost no flexibility in shooting positions compared to SX40 HS.
