Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Canon PowerShot S110 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing

Canon S110's 3" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
