"If Apple’s strategy succeeds, an increasing proportion of internet users will access through a gateway entirely controlled by a single company. For delighted iPhone users, this may seem like a great idea – just as it seemed like a great idea when Microsoft brought order to the chaotic PC market by developing the de facto standard operating system, and thereby acquired the kind of dominance that became so problematic. Steve Jobs and Bill Gates may have more in common than people realise."
John is sort-of right here. The difference is mostly in slightly deeper motivation. As Robert Cringely once said, Gates sees the PC as a method of transfering every spare dollar, pound and kopek into Bill Gates’ pockets. Jobs, on the other hand, sees what he does as a crusade for good taste.
