Is upgrading 720p to 1080p worth it?

I owned an HDTV set in 2002... it was pure shit by the time HD was the dominant format. The same will happen to you if you buy a 4K TV in 2016. Wait until 4K is dominant, then get one. They will be much, much better... and cheaper.

Hmmm. Well if so many people think it's a bad idea, then I'll definitely hold off on 4K until later.

Any recommendations on a good 1080p TV at like 55in or so?

back in February I bought a 50" Vizio E-Series Smart TV for $450 and i think its a really good TV.
