All you early adapters are crazy imo. Wait a couple years and then get a 4k. There is so little content that actually takes advantage of it, and the content that does is 4x the space (average 4k movie rip is like 80 gb), I see no reason to jump on it atm. 1080p still looks great. It's not like we're talking the jump from 480p to 720p/1080p which was night and day different.
It's comparable to people rushing out to grab the Iphone 9 when Iphone SE is just as good. In a few years top of the line qled/oled 4k will be the price of current 2ks. Just buy it then. you didn't NEED the 4k a couple years ago, why do you need it now?
