单选题NOBODY else in the computer industry, or any other industry for that matter, could put on a show like Steve Jobs. His product launches, at which he would stand alone on a black stage and conjure up a "magical" or "incredible" new electronic gadget in front of an awed crowd, were the performances of a master showman. All computers do is fetch and shuffle numbers, he once explained, but do it fast enough and "the results appear to be magic". He spent his life packaging that magic into elegantly designed easy to use products. In retrospect, Mr Jobs was a man ahead of his time during his first stint at Apple. Computing"s early years were dominated by technical types. But his emphasis on design and ease of use gave him the edge later on. Elegance, simplicity and an understanding of other fields came to matter in a world in which computers are fashion items, carried by everyone, that can do almost anything. "Technology alone is not enough, " said Mr Jobs at the end of his speech introducing the iPad, in January 2010. " It"s technology married with liberal arts, married with humanities, that yields the results that make our hearts sing. " It was an unusual statement for the head of a technology firm, but it was vintage Steve Jobs. His interdisciplinary approach was backed up by an obsessive attention to detail. A carpenter making a fine chest of drawers will not use plywood on the back, even though nobody will see it, he said, and he applied the same approach to his products. " For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through. " He insisted that the first Macintosh should have no internal cooling fan, so that it would be silent—putting user needs above engineering convenience. He called an Apple engineer one weekend with an urgent request: the colour of one letter of an on-screen logo on the iPhone was not quite the right shade of yellow. He often wrote or rewrote the text of Apple"s advertisements himself. His on-stage persona as a Zen-like mystic notwithstanding, Mr Jobs was an autocratic manager with a fierce temper. But his egomania was largely justified. He eschewed market researchers and focus groups, preferring to trust his own instincts when evaluating potential new products. "A lot of times, people don"t know what they want until you show it to them, " he said. His judgment proved uncannily accurate: by the end of his career the hits far outweighed the misses. Mr Jobs was said by an engineer in the early years of Apple to emit a "reality distortion field" , such were his powers of persuasion. But in the end he changed reality, channelling the magic of computing into products that reshaped music, telecoms and media. The man who said in his youth that he wanted to " put a ding in the universe" did just that.
