Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W730 is significantly lighter (39g ) than the Sony WX10 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX10 nor Sony Cyber-shot DSC-W730 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 WX10's 2.80" LCD screen is slightly larger than Sony W730's 2.7 screen.
