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 Sony Cyber-shot DSC-TX9 nor Nikon Coolpix P7000 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
Sony TX9's 3.50" LCD screen is slightly larger than Nikon P7000's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
