We received our Nest Learning Thermostat yesterday. The unit and its packaging are exquisite, simple, and well-designed. Other than a drill, the Nest includes everything you need to install it yourself, including a small screwdriver with four interchangeable bits. It took me about an hour from start to finish, and as you can see in the photo, I used one of the optional mounting plates to cover up the bare wall that was behind our old thermostat. Yes, the screen has a slight red tint to it, because it was heating the house when I took the photo. The free iPhone app (and web site) makes it easy to remotely monitor and control the Nest. So far, so good.
