In a BusinessWeek interview earlier this month, Apple CEO Tim Cook confirmed plans to manufacturer some of the company's Mac computers in the US. At the time, Cook didn't say specifically what models would be made in Apple's home country, but he noted that the plans went beyond mere assembly and have been in the works for a long time. He also revealed that the production wouldn't be handled directly by Apple, but that the company would be investing over $100 million to make it happen.
