You have never seen a thermostat quite like this. Designed by Tony Fadell, the man who designed the original iPod, Nest is the world’s first learning thermostat. Set the temperature in your home and over the course of a few days Nest will learn your climate preferences and start adjusting the temperature on its own. Since Nest is connected to your Wi-Fi network, you have the ability to control the temperature in your home from just about anywhere using a smartphone or tablet. Nest will also tell you when you are saving energy to help you save money. It will cost you $249. To find out more, visit nest.com or amazon.com.
