Of course one of the question is how much are you home. Being home generally 22+ hours a day means a lot of the IOT things are not needed. (I don't have a smart phone either, and my dumb cellphone sits in one place and I don't carry it, since my car has onstar if it breaks down I can call for a tow etc (included with onstar)). I still have CRT based TVs they still work. When I moved got rid of a 35 year old color tv that still worked except for the remote. The crt tvs still work so why replace?
We got rid of our CRT TVs a while back and upgraded to a 32 inch flat screen. It actually uses much less power. In that respect it was worth it.
In moving my DMIL to an aging facility we had to get rid of her CRT TVs. Most place would not take them as donations and the trash collections would not take them. We did find one place that would take them for free. One of the older sets cost $30 to give away to cover the recycling costs. It maybe worth the upgrade based on the hazardous waste costs and power savings.
