This is tightly coupled to the space I work in now (big data + healthcare) but if you look at what happened to Withings being acquired as part of Nokia’s Healthcare unit, a number of players are trying to get wearable more into the healthcare space - devices that your insurance might prescribe you to monitor your health following treatments to reduce costs. In cases like this (for example, being able to monitor how much someone walks after a hip surgery) they can potentially save tens of thousands of dollars for what is otherwise a very “cheap” tech product. But to need that they need higher tech/more reliable products than what the consumer could afford. Will be interesting to see where that lands them in a year.
