Perhaps you missed my point. The implication in the post I quoted was that Apple is coasting on the developments of it founders. That somehow, without earth-shattering new product categories, the achievements of today's Apple are empty.
Ford and Apple are just two of countless companies that have "coasted" on their founders' "inventions." Despite concepts like "creative destruction," for the most part a car company remains a car company, a computer company remains a computer company, a soft drink company remains a soft drink company, railroads remain railroads, entertainment companies stick to entertainment, etc. The job of management is to build atop the existing foundation. Most of the time that means more (and hopefully better) versions of the same thing plus new, related products that leverage the company's existing strengths. And founders die hoping that their "babies" continue to grow and prosper.
Steve Jobs didn't invent the smartphone, just as Henry Ford didn't invent the automobile. Ford and Jobs deserve credit for making their products into easy-to-use mass-market phenomena. Before Ford, cars were a curiosity for rich people. After Ford, everybody had to have one. Similar for Apple. Steve's dream was to take computers from something used by large corporations and operated by a small cabal of engineers and technicians to something that everyone could afford and carry around in their pockets. User friendliness. It Just Works.
Putting more computers into more hands than ever before... that sounds like just the Apple Steve would have wanted.
