Also, as Steve Blank points out (perhaps a bit too harshly), Tim Cook is a brilliant operator and optimizer, but very far from a visionary or brilliant product/marketing mind. So far, he's taken the foundation that Jobs built and made it sing.

But so far, the products Apple has launched under his leadership haven't actually been all that well conceived.

V1 of the Apple Watch was a confusing mess that didn't have a real, concrete purpose or place in anyone's lives.

With v2, they stepped back and focused a bit (on the active/athletic market), but it's hardly a breakthrough device yet.

Meanwhile, the iPad is (so far) falling far short of its potential to revolutionize computing.

All of this could change. But for me, despite the stock price, the jury on the Era of Cook is still out.
