It would be cool for things like this to ship with a dumb backup that can be easily replace if/when catastrophic failure occurs

I feel like that wouldn't send a great message about the quality of the product.It would probably be better for Nest if they had some sort of reliable failsafe you could easily access to make it much dumber.

you are right from a marketing persepctive it would be bad . y built in failsafe would be a much better way to go.
