The laptop's graphics chipset, the GeForce 320M that Nvidia makes especially for Apple, has a similar provenance. Designed by Nvidia engineers, who are mostly based in the company's Silicon Valley headquarters, the physical chips are manufactured in Taiwan by the aforementioned TSMC. ZDNet did the dangerous computer-opening work on a MacBook Air with the same chipset, and they'll , if you're interested.

All these components are of course just the next layer down from the computer. Where did the metal and plastics and silicon that made up the components come from? That's a question from another article. I do hope that the description here has given a sense of how global and disparate the sourcing needed just to put together one laptop is -- and that the "Made in China" label may only tell part of the story of any electronics you own.
