BTW, the last time that Apple manufactured primarily or exclusively in the US was probably a long time ago. Back in the beige-case era it did a lot of assembly in places like Ireland.
If they did this with the iPhone then the shareholder meetings would be pandemonium.
Doesn't hurt that it's also the device with the least need for miniaturization. Even if from the standpoint of an American it's a little insulting that they're giving us a device that a monkey could build.
This is the one product Apple could build anywhere on the planet and still make a profit. Will probably run between 30 and 50k for configurations that most effects houses would want in any case, so the higher cost of production is no sweat off their backs.
