Maybe... I also like the convenience of being able to simply turn on the TV and browsing through the program listings... and so does my wife.
While I'm pretty tech savvy, I still don't like watching TV on the computer (especially since I have a few nice big TV's), and going through the gyrations to send stuff from a tablet or my PC to a big TV is a bit of a pain (and virtually impossible for my wife to manage).
I do have a smart TV in one room, and a DVD player in the other room with smart TV capabilities, and I've fiddled with Hulu and NetFlix on those (my daughter's accounts), as well as Crackle... but they're tedious when trying to search for something.
I know what you mean by gyrations and the wife being stumped. I just pulled the 5.1 sound out our little TV room (one of the kids’ bedrooms) because 1) my wife cannot hear any difference from the TV speakers and 2) it’s just too complicated.
Have you tried Apple TV with AirPlay? It makes getting content on the TV from a computer or tablet very easy. But you probably need a Mac or iPad.
We have a computer hooked up to our TV. Wireless keyboard, mouse. It is pretty sweet.
But, we primarily use an Xbox to stream Netflix, Amazon Prime.
