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 Canon PowerShot SD3500 IS / IXUS 210 / IXY 10S nor Panasonic Lumix DMC-ZS60 (Lumix DMC-TZ80) 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 SD3500 IS's 3.50" LCD screen is slightly larger than Panasonic ZS60's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
