Tim Cook is masterfully using all of Apple's inertia to keep breaking revenue records. He's refining and improving existing products, but he's not leading a foray into a completely new category like Steve Jobs did over and over again. It will work as long as improvements in its core markets occur on a linear curve. It won't withstand an competitor making the product obsolete (for example, a possible transition from mobile to wearables - not that I'd put my money there, but still). Also, the Watch seems like it could have benefited from some Steve Jobs type of editing and distilling. That's the kind of product focused authority that such a company really needs.
