I was one of the first people that I knew that had a large screen (i.e. 52" which was large at the time) Flat Panel HD TV. It was a 52" Samsung LCD, bought it for $2200 about 10+ years ago. It was on daily duty in the living room for almost 10 years, now it is on duty in a secondary bedroom. It is still a fine picture, but nowhere near the new OLEDs. It is also not nearly as light nor thin as modern TVs.
Regardless, I got my $ out of it and will run it in some function until it dies.
To be clear, none of these newer advancements like 4k, HDR, wider color gamut, etc, are nearly as revolutionary as the step from SD to HD resolutions.
