If you were to disassemble one of the new 21.5-inch iMacs that Apple has recently started shipping, you might find a tag that says "Designed and assembled in the USA." While many industry experts and other sources think this is a sign that Apple may return to manufacturing based in the United States, the real proof comes from Tim Cook, who is expected to announce that one or more new Mac models will be built in the U.S. instead of overseas.

Apple, however, may not be the one doing the manufacturing. Instead, the manufacturing may be contracted to a third party. Apple does have a few small manufacturing facilities in the U.S., but it's unlikely that it intends to enlarge any of these facilities to meet anticipated demand. Instead, Apple may be working with an existing manufacturing partner that is willing to enlarge an existing site in the U.S. or build a new facility here.
We'll find out the details tonight when Brian Williams interviews Tim Cook on NBC (10 pm; check your local listing). Tim Cook also mentioned in a Business Week article that, "Next year we are going to bring some production to the U.S. on the Mac."
Likely candidates are the iMacs, Mac minis, and the new Mac Pro that is expected next year. The Mac Pro would probably be the easiest to build here, followed by the Mac mini. The iMac would have the largest production runs, which could provide an incentive to bring production here. We'll have to wait and see.
