All I want is the screen
The display of a "TV" is the biggest and most expensive part. I want this to be the dumbest, too. I don't want it to be dependent on the whims or mistakes (or cynical marketing) of some distant third party. I don't want to have to upgrade it, or replace it, merely because someone, somewhere, flipped a bit in a protocol and made it obsolete.
I want the smarts to be in a separate box.A little £50 add-on that can be changed every couple of years if necessary, to keep up with the tech, That also helps in since it stops my costly display from containing more parts (or points of failure) than necessary. So that a badly soldered SMD that only deals with networking, or the remote control, doesn't mean having to toss the whole shebang.
With pricey kit, dumb is good.
