I credit Jobs with obsessive attention to detail. Legend tells that when engineers brought him the iPod prototype and swore it couldn't be made any smaller he didn't even switch it on, he just dropped it in his fish tank and saw bubbles of air come out, then told the engineers there was still scope to make it smaller. Whereas Tim Cook is only fixated on whether it can show an animated poop icon.
