There are many things in this article I feel compelled to attack or nitpick about. But just to highlight one: the assertion that "the big problem is that Apple’s last hit product, the iPad, came under Jobs and launched six years ago".

That ignores the Apple Watch, which has basically created a new product category and proceeded to immediately account for more than half the total sales in that category. The Watch has outsold the iPhone during its early days, as well. For any other company, this would be reported on as a great triumph. Unless you have wild fantasies that Apple is supposed to magically produce an iPhone-sized business every two years, even though no other company in the history of money has ever produced an iPhone-sized business even one time. Double-digit millions of units of sales, first year, for a brand-new product that nobody's ever spent $400+ per unit on is pretty good.
