How does it do in the rain? If it gets stuck with me in the pouring rain for an extended period of time will I have to worry about it breaking?
It will be fine, assuming you keep it in the waterproof case.
The case is completely waterproof, but it's worth mentioning that I brought one on Tough Mudder this year and in the really cold water, it gets condensation between the case and the lens. Watch out for that.
@ Angus - they make an anti-fog insert that is said to prevent that from happening.
