Google is finally giving us another Nest Learning Thermostat. It's a long-overdue update, with the current generation now nine years old. Rumors say the 4th version of Google's smart thermostat will cost nearly $300, a price that, only a few years ago, I'd only dream of paying for a thermostat if it crooned me lullabies at night or offered a J.A.R.V.I.S-level administrative assistance.
