There will be plenty of time for analysis of what now happens at Apple and whether the company can retain is extraordinary leadership of the world of technology, but my first reaction to the resignation of Steve Jobs as its chief executive is sadness.
Mr Jobs, at the age of only 56, stands as one of the great business leaders – arguably the greatest – of the postwar era. For the past 30 years, he has not only led the wave of technological change emanating from Silicon Valley – the personal computer, the internet, the tablet – but stamped his aesthetic on the world.
He has combined the iconoclasm and creativity of the rebel entrepreneur with the ability to assemble a world-beating manufacturing, design and marketing team around him. In the past few years, Apple has been not only unbeatable but hardly even matchable. Its competitors have fallen by the wayside in frustration.
