I was thinking about how cumbersome it would be to change phone platforms if I got tired of iPhone or Android, and then how much effort I wouldn't want to spend if my Amazon device controlled all the lights, TV, audio, and temperature in my house.

I think more than the individual effort of changing systems, its the network effect that keeps people tied down. A new platform or service could disrupt that easily. What if you didn't need to carry a phone (VR/AR/?), or what if all homes came with those systems built in.
