The Nikon Coolpix AW110 is a fairly minor update to 2012's AW100, as you may have figured out by the incremental model number change.
If you're looking for a rugged camera, but don't want to sacrifice on-the-go sharing, the Nikon Coolpix AW110 is a good place to start.
The Nikon Coolpix AW110 is rated to survive being underwater down to 59 feet and drops of up to 6.6 feet along with being freezeproof and dustproof; has built-in GPS for geotagging among other things and Wi-Fi for easy shooting and sharing with iOS and Android devices; It is well priced considering its features and durability specs.
While its shooting performance is good; the camera's spongy buttons might slow you down a bit and the camera's slow lens requires a lot of light to get the best shots.
