I think our conclusion on the S110 says it all: "But, as DigitalCameraInfo says, "if you’re totally in love with touchscreen technology or you think WiFi will really be a benefit to how you shoot," you should get the S110. Otherwise, the S100 remains a great camera, and a gdgt Must-have model, and it sells for $150 less than the S110."
The step from the s100 to the s110 was very incremental and the only big feature change was wifi and touchscreen.
Thanks I really appreciate the advice! Hello from AOL ;)
