I was really hoping to see software upgrades available to existing nest customers. I don't need a thinner version with a larger screen (it's nice, but it's not a smartphone and I don't think most people will care). Tesla gives you a better car with ota firmware updates. How come a thermostat startup with Google's resources can't do the same thing or better?
