too early to tell. so far, we know he hasn't messed up the formula and financially he's off to a great start. but jobs faced steeper hurdles right away bringing the company back from bankruptcy and reinvigorating morale within the company. jobs then successfully invented new product categories and much of the success apple is enjoying comes from an expanding smart phone market, which you rightly point out that cook is doing a fantastic job of addressing. the apple watch will take a couple years to see if it's really a success. lots of fanfare so far, but it could fade in popularity like the iPad which, if you recall, was an incredibly fast growing category. the iphone franchise, just like any other franchise, cannot last forever. and to find another product category with growth like that is going to be a very, very difficult thing to do. i personally believe that SIRI will be the most important category at apple over the next 5-10 years. voice interfaces, without the use of a 5" screen will be the next most important UI/UX in computing. and i would not currently bet on apple to be the best at delivering that. i'd say cook will have to be measured by his ability to dictate and keep up with technology trends, not just manage the supply chain. but you're right, he's done a great job of that for sure.
