It would be nice to have a high resolution tv of course, but at this time even the Jones's would be kidding them selves.
Are there any movies/tv stations broadcasting at 4k resolutions? no. Broadcasting is having bandwidth issues relaying 1080p playback as it is.
Its a step in the right direction, but until infrastructure is upgraded for demand, it will be a very long time until these kind of tv's will be given their respects.
