I think it falls into a sort of "home automation/monitoring" model. As we move further into the "Internet of Things" spectrum, Google and Nest are just securing their place. Think about how Microsoft and Sony's gaming platforms continue to build on the idea of being the only device you need for your TV. I wouldn't be surprised if Nest sought to acquire someone like Fitbit for the same thing, monitoring health/fitness via the bracelet or weight scale; or an automated garage door opener company (if they did monitoring/diagnostic work when the car is in the garage).
