That is the question.
I'd like to put a 50" or 55" LED HDTV on my gift list this year to replace my aging plasma - lots of options out there but I've narrowed it down to Samsung or Vizio 50-55" with Smart TV functions. I can't imagine I'll use 3D but I won't rule it out. From everything I've read, at 8-10' viewing distance (not much I can do about that in my living room) 4k won't appear any better than 1080i/p. But, I tend to keep TVs for a LONG time, so I don't want to be stuck with out of date technology if 4K really takes off.
I value picture quality for movies over sports, and audio is run through a receiver so TV sound quality is not an issue. Any thoughts on 4K or 3D for home theater?
Edit: Oh yeah, target price around $700-900. Considering Black Friday sales, I think I should be able to find what I'm looking for in that range.
