Even as Apple promises some US-assembled Macs, Foxconn, one of Apple's largest manufacturing partners, is reportedly looking to expand its North American operations in the near future. The Taipei-based manufacturer, which already has operations in California and Texas, cites growing customer demand for American-made devices as the reason behind the shift. Foxconn Chairman Terry Gou said at a forum last month that the company would be interested in bringing US engineers to Asia to train them in manufacturing before sending them back to work in US-based Foxconn facilities.
