>if it's not precise enough for doctors, then it shouldn't be touted as something my health insurance foots the bill for.
That isn't true. There are level of information. The information I need to decide if I need to see a doctor or not is much lower quality that the information my doctor needs to make a diagnosis.
Health insurance should foot the bill if ultimately the data is good enough to get people to the doctor when the problem is small and easy to treat. If a 100 dollar device for everybody allows them to turn a few $200,000 dollar procedures into $10,000 treatments that will be a big win and they will. (note that the above two may or may not be related)
