Three years ago, Tim Cook very memorably said that although Apple was selling $40 billion worth of products every year (that number has since more than quadrupled), all of Apple’s products could fit on a dining room table. That amazing quote was slightly disingenuous — many of Apple’s products are virtual, and take up no physical space at all — but it still made a point: Apple chooses what it does so carefully that everything has its place. What Cupertino doesn’t do is just as important as what it does.
It’s all interesting food for thought, to be sure, but what if we took Tim Cook’s table metaphor and broke it down? For every foot of table, how much money does Apple make on each product?
