This is simply like mutilating your IPhone. If a case such as this were to come out I can only imagine how many people would kill their IPhones with chalk dust. It is hard to believe that anyone would even think that such a case would really take off for the IPhone. I will tip my hat off to them for their creativity, however in the practicality department they have an no sense at all. The chalk from everyday use scribbling onto the case would eventually drown every little nook and cranny of the IPhone with chalk dust. Another issue would be why would people carry a phone with chalk and scribbled writing on it, which would all simply smudge in their pockets. Let us keep our fingers crossed that this either does not get released or that their are some dramatic improvements with it.
