I think I acknowledged the ease of removal, but in the market I am in - moving back home to Portland, Ore. - most of the homes that have Nest products have multiple Nest thermostats, Nest locks, and Nest smoke detectors. As the article alludes to, it is a product line that contractors were going all-in on for quite a while. There are an abundance of wonderful homes that do not have these gadgets, so using one data point to limit my search can be helpful. I am looking at a lot of homes while working full-time in a different city. Sure, I may miss the perfect house, but I doubt it.
