People would either need bigger TVs and/or to sit closer. It's the same with 1080p vs. 720p. Ironically, I might be better able to make use of 4k video on a computer since I sit so close. I find video to be a bit soft on the iPad 3 and Retina Macbook Pro because both have to up-convert 1080p video. I expect to have a 4k or so 27-inch monitor in a few years, and would love to be able to watch native video on it. I would need to both sit much closer and need a bigger TV to make use of 4k video. I still have a 720p plasma because where my couch is, it's almost impossible to tell the difference between 720p and 1080p.
