> Then there's cheap in terms of wringing cost out of a commercial product

This is a very astute distinction that hobbyists wanting to go from Arduino to production often miss.

I went from the basically cost-unconstrained world of Medical Devices to wearable consumer sensors (e.g., heart rate monitors, etc.) and it was a bit of a shock to see just how much impact cost had. I mean, you know that in a "theoretical" sense, but it's completely different when you are dealing with it on a daily basis.
