Look, BusinessWeek pulled the 3 million figure out of thin air. Apple doesn't leak that kind of info, ever. My guess is that a few editors over there had recently bought some Apple stock given the recent run-up, and they were looking for a way to inflate it even more. So, they came up with this 3 million number, which certainly sounds impressive and has not only contributed to the hype, but become an oft-believed rumor on the internet. Mission accomplished.
