I just thought of something! Can you replace the keyboard and front casing on the new Macbooks? Cause I was thinking if you could not they will eventually get worn out and dirty, and possibility turn in color! Also I know that you can get replacements on ebay for the old Macbooks so this could effect my purchasing decision. And yes I know its uinbody but it IS also made of different interconnecting parts. So does anyone know? I sure hope you can.
