The Rebirth of Silicon Valley Hardware Manufacturing

Are we experiencing a rebirth of Silicon Valley hardware manufacturing? High volume manufacturing of hardware is not something commonly done in Silicon Valley, with much of that work finding its way to places around the globe. But a large amount of new product development, prototyping and low volume production seems to be firmly positioned in the Valley.
