> I had a coworker whose brother is on the iPhone hardware team and they have a lot of trouble with samples coming back from manufacturing with the wrong resistor here or a missing capacitor there to save a few bucks, because the factory sees it as overengineering, but doesn't understand the purpose it's built for.

I find that story utterly implausible.

The day Foxconn makes unapproved changes to Apple designs is the day that...well, never.
