>If Apple has pricing power because people don't move to competitors I'm not taking sides, or claiming I'm an expert on economics, but isn't the question with monopolies always "what is the market, and what are the competitors"? If you accuse someone of being a monopoly, they will always define their market as widely as possible, but if you are an antitrust lawyer trying to win a case against them you will define it as narrowly as possible. There's always a sufficiently wide or narrow definition for either side to win. And every business has some pricing power and some friction for their customers. Everyone talks about investing in companies that have a "moat" which seems to be understood as something more than many companies have, but less than a monopoly.
