Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W220 is 20g lighter than the Sony W290 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W290 nor Sony Cyber-shot DSC-W220 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 W290's 3.00" LCD screen is slightly larger than Sony W220's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
