its the same as anything else, it depends on luck, you can drop it from 500ft into grass and it may take 5 pictures before shuttig off for good, you could drop it 5 inches and damage internals.
i used to ride flatland bmx in parking lots with a minidisc player, and fell off my bike landing on it in my pocket and it still worked fine after multiple times, 2 years after i bought it, i slid down a hill in grass, the lcd screen broke.. but falling onto asphalt did nothing.
it finally started to skip and not work as great, so i finished it off.
it was mostly plastic, and since it was a minidisc, its like a cd player half the size
moral of my story, you can abuse the hell out of something and itll come back for more, but if you abuse it in the wrong way, its game over.
