My TV is a 65 LG 1 K unit about ten years old. It seems to work fine, for me. The prices on new ones has really come down, I glance at them in Costco (as they intend me to). My wife even offered to get one for me for Christmas, and cheap me thinks "Nah, the old one works OK, and I'd have to spent time mounting the new larger one.".
I don't use Roku, or Apple, or NF. We had NF for a time and that was OK but then they tightened up the family sharing gig. I get Amazon on it, I rarely find anything there to watch. I spend some time with youtube, just the regular videos, some of which are quite good. I'm interested in tanks and the Tank Museum has some nice ones on WW 2 and later tanks.
The French term for "tank" is "char" and the German term is "Panzer". The English term has a funny origin most of you know.
