And, as someone who lives in the Northeast (where it was -20 F on Saturday night) and travels a lot, reliability absolutely trumps features no matter how cool. And I've heard way too many stories, however anecdotal, about Nests not doing what they're supposed to to use one even if you gave it to me for free. (I do have a programmable Honeywell but it's very basic and I just make a point of changing the batteries every year.)
