I have been using a space gray MacBook for the past week or so and I just noticed that there is considerable wear (i.e. scratches, paint coming off) inside the power port already. I am not too worried regarding functionality, I am just a bit surprised that the port looks kind of rough after one week of normal use. Makes me wish Apple had covered it with a thin plastic layer like it did with the headphone port. How are your ports holding up? Anyone who has noticed something similar with their space gray/gold/silver MacBook?
