That article appears to be discussing Apple's avoidance of taxes on non-US sales: "By running nearly all its non-U.S. sales through the Irish subsidiaries, Apple also avoids paying taxes on sales in other countries, including the U.K., Germany and France, the report said." From what I can tell, this 'double Irish' arrangement does not apply to US sales. Edit: Neither the Forbes article nor the Macworld article are discussing US sales, only worldwide sales.
