I saw one yesterday in costco and tried it out a bit. seemed to take decent pics and the controls were easy. I liked how the compartment door latched securely and it not easy to open (good thing). Screen is nice and big. Trying to justify the cost over some lower priced water proof cameras like the Fuji XP20 ($117), expecially when only going to use this a few times a year.
I've had one for about 3 months. It's really handy to have in your pocket. I'm impressed with the pictures and especially the video. I've tried it underwater while fly fishing. Pretty cool. It's very easy to use.
