Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (63g ) than the Canon SX230 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix L31 nor Canon PowerShot SX230 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 SX230 HS's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
