In "Apple Store Reality Check" in TidBITS 410, Adam made a mistake in calculating how much money the Apple Store would contribute to Apple's bottom line if you assumed that all of the Apple Store sales would otherwise have gone through the dealer channel. In short, the additional 15 percent that Apple makes on direct sales should have been applied to the $144 million in orders, resulting in a $21.6 million profit above what Apple would have made if those sales came elsewhere. Thanks to alert readers Clive Bruton and Peter Schoenrank for setting us straight.
