For work this year we bought a Panasonic Lumix DMC-TS3. Waterproof to 40 feet, dustproof, shockproof when dropped from 2 meters, orange so it would be easy to find, with reflective orange tape added just in case...

it was dropped in the wilderness, in its black case, and was never seen again. We had to buy a replacement.

Great camera by the way, pocket-sized, around $250. GPS tags the photos, shoots HD stereo video, etc etc.
