I don't need it, but it would be a nice upgrade from my 47" Lg 7 year old 1080p. I just bought a house (very small house) this past summer and I only have one TV right now. I am trying to keep it as minimalistic as possible so I don't need / or want a TV in multiple rooms since it is only me in here.
My theory would be spend good $$$ on a TV if it is going to be my one and only TV. It's this, or a Samsung QLED which the higher end models actually are close in price to OLED (QLED is still LCD, just very fancy old tech that is brighter than OLED). I foolishly missed out on some black friday deals but hoping that the current OLEDs drop in price after the CES 2019 and maybe around Super Bowl.
If purchased, I also will be upgrading my Xbox One to the One X to get the true 4k experience.
