Apple is amazing when it puts its mind to hardware for which there is an "ideal" Form; the macbook is the "perfect" form for a laptop, the iPhone is the "perfect" form for a smartphone.

Take watches however, there is no one perfect form - different needs demand different forms. Or cars, or fridges or planes.

So yes it may not be computers, phones or tablets, but the number of multi-billion dollar aspirational hardware products that Apple will be good at is not by any means a large number.
