Not sure if anyone cares about my opinion, but I'm giving it anyway.
I was in Future Shop over the weekend with my son and decided to go take a gander at the newest 4k sets. I saw last year's crop a few months ago when there was just Samsung and Sony, but now they had LG as well. What a beautiful picture. Just jaw-droppingly beautiful, like looking out a window. There a highly-rated LG 55" 4K on sale right now for $1780. I'm looking for something around 65", but still that's a damn good deal.
Not only is the picture sharper but the colour is better. It will take porn watching to a hole new level (<- see what I did there?).
All joking aside, we are now approaching the resolution of film itself. Doesn't that blow your mind? Watching a movie with the quality meant for a movie theatre on a screen less than 100 inches diagonal !! If that doesn't get your gadget geek on then you need to turn in your man card right away.
My wife freaked on me when I told her about 4k. "We're not buying all our movies again". LOL. She's calmed down now. All I know is, come Christmas 2015, I will be shopping for a 65" 4k TV, 4k Blu-ray player, and a 4k copy of "The Fifth Element".
Shut up and take my money !!!
