I have to admit, I don't really understand this point of view; the selling point of a "smart" TV is that it does the work of integrating computing ability into the television viewing experience for you. Personally, I stopped trying to use the internal processors of my television sets a long time ago. Right now, my TV is simply a gigantic monitor hooked up to my (HT)PC.

I never listen to my TV's built-in speakers, as I run all my audio through speakers connected to my PC. I practically never use the TV's built-in tuner, as the tuner I purchased for my PC often does a better job pulling in stations. And strangely enough, my PC's DVD player does a better job playing movies than the dedicated DVD player I bought years ago...

It appears to me that the fundamental issue here is that smart devices are integrating lots of components into a single indivisible mass. If you find this design displeasing, the solution is to disintegrate these components. In particular, if you want to combine a TV with a computer, then you should literally combine a standalone TV with a standalone computer. Don't buy an all-in-one TV/computer and expect to be able to use the two halves separately...
