It's looks great and the interface is clean, but it has major technical flaws:
1. It has "activity sensors" that will decrease the temp after 2 hours of inactivity. What if I"m watching a movie in the other room? Be the end of the movie it'll be cold in the house thanks to Nest. And I think most people's thermostats are not in a location that faces their living room.
2. It has no ability to predict your leaving/returning home. With my programmable, I know that I leave at 7 and arrive home at 6. I can adjust the thermostat to anticipate this event. The Nest won't. It'll START adjusting when you arrive home.
What it needs to do, is sync wirelessly with a toggle you keep on your car keychain. When the toggle is gone, you are gone. That way, it learns when you leave, not when it "thinks" you are gone.
