I've broke two. The touch screen is wonky and sometimes thinks it is being depressed even if it isn't.
I wouldn't buy it for an mp3 player, I wouldn't buy it for the camera, I wouldn't buy it as a cheap/portable solution to both. Even when I had it, I still carried around a camera just because if there was something I wanted a picture of I could get a better picture faster (I love my sd1000)
