About 10 years ago I interviewed with a small company (not nest) that was building thermostats, primarily for hotels. They had a proprietary method to raise and lower the temp based on if there were people in the room. They had a lot of grandiose plans, one of which was the possibility of ads on the thermostat. I can sort of see it, I would suspect people look at the thermostat more often in a hotel room. But the goal of Nest is you STOP looking at the thermostat. Theoretically once it learns about you, you shouldn't really have to look at it again. As for ads elsewhere, as long as I get something free in return. And, yeah, more than one sci fi author has forseen a future like that.
