Nice that the price is coming down, but they still offer bad value due to the lack of content
Yep, as long as there is no 4K content, and that might take a while (no reason to start shooting everything in 4K, not untill it is the mainstream).
Its just smarter to get a full HD tv now for 300 and then a quality 4K Tv for 500 in... say 2 years when its actually a mature technology (thats why companies charge crazy prices for new tech, so that for a while it feels like only rich people can afford it, same as when iphone started out as a VIP product).
Personally, untill GPUs cant handle 4K, I can wait. I have watched movies in Dvd and blue ray quality, and while i can notice the difference, its not worth paying a 50% price increase for EACH movie I want to buy.
