Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P900 is significantly lighter (511g ) than the Nikon P1100 which may become a big advantage especially on long walking trips.

Unfortunately neither the Nikon Coolpix P1100 nor Nikon Coolpix P900 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
