They probably could but the users don't want to pay the premium for that. PC users that always bring up the cost argument remind me of the guys from the mad max movies who build those insane looking frankencars. Why buy a BMW when you can get the parts to do the same thing from miscellaneous cars. Most PC users do care about design but not to the levels of detail that Apple puts into their computers. They want to spend the money where it counts for them and that's on the guts.
