I was very early adopter of HD. I bought my first set for $1600 in 1999 IRC. Was too soon but I enjoyed it. First year or two there wasn't much content. The major networks had to be forced kicking and screaming into the digital age by the FCC. I don't see that happening with 4k. There is no frequencies to recover and auction off. Not everything they throw up on the wall sticks. How many times are they going to throw 3D at us? None of my TVs have 3D and I don't miss it at all.You realize people said the same thing years ago?
Pfft HD? Yea when all my channels are in HD THEN ill upgrade my crappy sdtv for a hd one...
Even better,
"I cant really tell any difference, looks the same to me!"
There is a lot to work with 4K. I certainly wouldn't spend a ton on it now.
