Thanks for the info. Why did Jobs spend so much energy defending assemblies in China instead saying most is made in the US?
This is way back when Jobs was alive, Obama ran into him at some conference or similar meet. Obama asked Jobs why they were making stuff in China (along with other companies) and what would it take to bring those jobs back. Jobs patiently explained the case to Obama (as one would to a child). China has the infrastructure setup whereby large factories are clustered together with dormitories for workers, and rail and shipping, and parts suppliers. They can pull together thousands of workers at a moment's notice if required. That infrastructure does not exist in the States; it did in a bygone area with company towns. Jobs told Obama that it would be super expensive to set up that sort of infrastructure in the States, and the federal government impedes that with bureaucracy, taxes, and inane laws.
Apple under Tim Cook has made a huge investment in building computers here in the states, locating in areas with a large pool of tech workers near universities and shipping points. Hence, the SF Bay Area in northern California, Austin Texas, and a few other states (newest in Arizona). It has cost them many hundreds of millions versus the savings if made in China. It was mostly the high-end Mac desktops at first, with other Macs like the iMac saying "Assembled in the USA", but then shifted to being made here within the last few years. Say what you will about Tim Cook, he brought manufacturing back to the USA. Few other tech companies are doing so.
