Re: Colour me surprised
That puzzled me too. I can buy that it's more efficient or has more features, but I don't see how it can be easier to use...?
EDIT: I was making the assumption that normal people just set their favorite temperature and never ever change it. I now remember that American houses typically have crap insulation, which means that heat is perpetually bleeding out of your house, and people save money by not heating whenever they're not at home.
