Goldman Sachs said it believes Apple will sell more than 14 million iPhones through 2008 based on results from a recent buying intention survey. The investment firm forecasts sales of 4 million iPhones in 2007 and 10.5 million in 2008. The consumer survey—conducted in the U.S., U.K., China, and India prior to the iPhone’s official unveiling—found that the number of potential iPhone buyers is equivalent to 75% of the installed base of current iPod owners. In the U.S., where Apple ranked as the No. 4 most desired handset brand, 71% of respondents indicated interest in a potential Apple phone. The survey also found that a number of consumers are willing to switch carriers to get the iPhone, with 30% of U.K. respondents and 15% in the U.S. suggesting that they would switch.
