We had a ton of fun with a second-hand Fujifilm XP70 while on vacation but didn't treat it too well in the salt water. It's OK but no longer sealed properly. After my usual extended review reading frenzy, I selected the new Olympus TG-4 as a replacement. Very impressed. This is the camera to have with you. Even has an optional accessory ring light for close macro. Super bright f2.0 lens with pretty nice bokeh for a point-and-shoot. And very cool wifi capabilities. Also, it shoots RAW and up to 15m under water at that.
With all the competition from smartphones, the traditional camera manufacturers are stepping up their game.
