I know here on the forums a lot of us (myself included) have made fun of Apple watch cases. I just thought of why/when one would be practical. When riding a bike. Think about it your biking and you fall or slip or what not what happens to your bike/ horn/ bell/ whatever's on your bike? It gets torn to ****ing shreds! Now realize this I would not feel comfortable going for a bike ride with an Apple Watch not in a case. Last thing I would want is to scratch the living **** out of it. Thought, comments? Any other times you could think of you would want to have a case on your watch?
