We (https://supplybetter.com) get asked the China vs. US question all the time and my answer is usually "your mileage may vary". It's a great post by the Flow team, but where to source your manufacturing supply chain is highly dependent on the type of product being built. For instance, the product and vendor certifications required for aerospace, defense, and medical industries are a much larger influencer of where to setup a supply chain than in the consumer hardware space. If you're developing a high-end consumer office product like the Flow team, then it probably makes sense to do the majority of the development domestically. The Bay Area is a great place to prototype hardware, and there's a large fraction of potential beta testers and software talent for them to tap. But like I said, YMMV.
