The iPhone was immediately dubbed “the Jesus Phone” by bloggers. But Apple’s competitors emphasized that, at $500, it cost too much to be successful. “It’s the most expensive phone in the world,” Microsoft’s Steve Ballmer said in a CNBC interview. “And it doesn’t appeal to business customers because it doesn’t have a keyboard.” Once again Microsoft had underestimated Jobs’ product. By the end of 2010, Apple had sold ninety million iPhones, and it reaped more than half of the total profits generated in the global cellphone market.
