Is this not the coolest home thermostat you've ever seen? Of course, designed by a former Apple VP. The Nest Learning Thermostat senses when you are home, is simple and easy to program, and much better looking than those boring cream grey ones that are so unstylish. And its controllable via your iPad, iPhone etc when you are away from home. Smart eh!
Definitely on my list of 'must haves' for our new US home (when we find it).
