Have had one for over a year now, i got the older version of this with ~10mpix for about £250.
I use it sea kayaking and on the river and i surf, its survived everything. I got my best videos shot ever of 20ft long basking sharks underwater right under the kayak with this wee thing. Its permanently attached with a karabiner and 2 ft shock-cord. Much more portable than my big canon and i can use it 1 handed sitting in surf as well.
If i had to get another compact camera you don't have to worry about i would get another one.
