Jobs admired Sony, which introduced and won several new product categories. But when the founders left, esp Morita, this stopped, though of course they remain successful to this day - they just aren't creating new product categories. Cook, as an operations guy, will keep things running. But can Apple lead new product categories under him? The Apple Watch seems to be showing he can... If so, it's something even more impressive than biggest cap etc. Something Sony didn't manage. The iPad is dying not because of longer upgrade cycles, but for the same reason desktops are: it's less convenient than a phone (or watch).
