Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S70 is significantly lighter (440g ) than the Canon SX40 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S70 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.
