I continually come back to the thought that typical consumer software practices - be it games, apps, cloud services, etc - where you iterate quickly and don't always work out the bugs or design scales well to things like Nest protect, etc. For me, anything that ends up in a consumer home device should be solid from the time it is purchased and not require software updates to work right.

This leads to another concern of mine -- are places like fb, apple, Google, etc. capable of creating stable v1 products for the home.

With Nest, the initial thermostat seemed to work well. Original Dropcam works well. There have been questions since the acquisition of both companies.
