Yes, DH sees having all of this stuff (like Nest) as a way to simplify, while I just see it as one more thing to learn. A thing I don't want or need to learn, like algebra! He gets excited about gadgets. Nest will now know when I am heading home and raise/lower the temperature accordingly because it's synched with my I Phone. The test will come one day when I want to shut off the heat and open the windows, or worse, put the AC on.
Funny, my kids are a bit Luddite for their generation.
