Nothing that special from a technical point of view - but... Some years ago one would use a 5-axis CNC mill to produce car engine blocks, but not for mass production for consumer products - everyone would have used plastic for that. The iPhone was the first phone out of aluminium. Also the using a full block of aluminium to mill a Apple notebook body out of it in mass production, was never though before. (Sure higher quality traditional watches were always made of high quality metals)
