And note that it comes down to what threat level it actually faces. I take my perfectly ordinary smartphone into the wilderness. It's never going to tumble down a rock face both because you'll never find me on one but because I have it lanyarded to me. It's fallen a few times, but the lanyard has kept it from hitting the ground.

You have to balance the cost of it being rugged vs the expected chance of the ruggedness keeping it from being damaged. And for most people the tradeoff isn't worth it.
