"The whole product is going to be very costly to sustain. It will need to use a different kind of biz model to sustain this line. And probably find a special customer segment for it.Google cannot be the one producing the modules. They need to let 3rd party vendor produce it, and absorb the cost. Also 3rd party brands will be known for their technology, and people will be willing to buy the modules more. Imagine... camera module from Nikon.Health sensor module from Withings...Customers will choose to buy parts that they trust and believe, and have existing cloud data."
