Re: GoPro or Point & Shoot
I go with Point and Shoot too.
I have Sony DSC series which I bought more than 3 years ago for kayaking, fishing, and family trip and still doing very well. Good pictures with 1080p HD video format. The camera is waterproof, dust proof and child proof (so far). The winning feature of the GoPro is just the mounting.
I bought a small magnetic Gorilla Pod and have the flexibility to mount the Sony on any surfaces.
All these point and shoot cameras are waterproof but they are no Michael Phelps. So get some kind of cheap flotation device to keep them from sinking into the abyss or to your toes.
BEWARE...Once you switched, you can't switch back. :
