i have a first gen nano and i have never used a case for it ... why : i think it takes away the "look" of it ... its scratched as hell ... little scratches ...
Always. It seemed to me to have been a sensible precaution; things fall, they topple, they slip. You drop them. And they break. Accidents occur. I have always had a case for mobile phones and iPods, it just seemed the sensible thing to do.
