I’m about to get rid of my ageing “dumb” TV and not replace it. Everything comes in to my laptop now, so any monitor and set of speakers to plug it in to will do.
My prediction is that this is going to be the end of the line for TVs as stand-alone hardware - just like most people don’t really have stand-alone Hi-Fi systems any more.
My biggest regret was getting rid of a perfectly good portable CRT TV that would have been ideal for pre-7th generation gaming, just as they stopped making good quality CRTs.
