As a family who's away a lot on weekends, the idea of having a thermostat be able to learn our behavior and adjust accordingly for energy savings is pretty cool. I always try to remember to turn down the thermostat prior to leaving, but sometimes the craziness of trying to get a family up and out gets in the way. Not sure I agree with the founder that the look of NEST is more appealing than a simple white digital thermostat on the wall. But I did like what he said about their battery strategy in terms of getting the longest life out of their units.
