Has anyone seen this Nest thermostat before?Please Log In to view this link! I am very interested in it, even though the initial cost seems a bit high. It seems like a really technologically advanced thermostat that is smart about how it works on its own. You can control it in person or from your smart phone, and pretty soon, it'll teach itself a system or routine (ie: when you leave the home, when you come back home, when your bedtime is, etc.). Sure, it's always nice to really be in control of everything, but this seems very Handy. What do you all think?
