4. Nest Thermostat
With the increasing usage of smart devices in our lives, it will not be long until our homes become interconnected with the use of smart household appliances. Nest Thermostat served a simple enough purpose, which is to cool and heat houses. However, the device came with a color display and software found in smartphones. Google bought the company that made Nest two years ago. With Nest as a basis, Google wishes to design future homes that will be equipped with smart technology.
