The PowerShot S110 is an incremental upgrade to the previous S100, offering somewhat faster autofocus performance, a touchscreen, and WiFi. But image quality is unchanged, and, as DigitalCameraInfo puts it, "the S100 offers the same performance for less money. Itâ€™s as simple as that." That doesn't mean the S110 isn't worth considering. Gizmodo points out that, given its diminutive profile, the S110 "packs in more quality per square inch of camera than any other point-and-shoot on the market today." But, as DigitalCameraInfo says, "if youâ€™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 can be had at a significantly lower price than the S110.
