Unfortunately from a business perspective it's very hard to argue for this stuff since goodwill doesn't have a definable dollar amount but the engineering time to extract this and getting it working extremely definitely has a cost.

The back end of this smart crap is very likely inextricably intertwined with Google's internal services.

Remember Google exists to harvest data which means the important part of this thermostat is not being a thermostat but recording when you're home, what temperature it is, if you're awake etc etc.

I will say, MS make a decent mouse.
