I'm actually with you on this one. I want my TV to just be a display, it has one job and that is to take an input, decode it and display it. It should just do that one job well. I don't even care about the sound.
I tend to agree with this, for the most part. My home theater system consists of components that only do one thing--the projector only projects an image on the screen and the receiver only outputs sound to the speakers. Only the streaming devices (FireTV, AppleTV) have connections to the network and if one or both of them fails, I can still watch movies on Blu-ray or from movies ripped onto my media PC. Nothing is "smart" and everything has separate remote controls that all must be used together, but that's the way I like it.
The one "smart" appliance I have that I actually like is my dryer. It has the ability to notify me via a text message when it turns off. Since I'm rarely in earshot when it's running, that's a nice feature to have. If that feature ever stops working, it won't affect the basic operation of the dryer.
When shopping for appliances, I tend to favor reliability and long life over gee-whiz gizmos that I'll never use anyway. That's getting harder and harder as companies continually look for ways to build things more cheaply, sacrificing robustness in favor of gizmos that are often just software that doesn't add to the material cost of the product. I'm currently shopping for a new dishwasher and have found that even the high-end models from brands like Bosch and Miele have flimsy dish racks that look and feel like they won't last long.
