We bought a 55" 4K TV from LG and we love it! The Way it up-converts "regular" HD content alone for us has been worth it. It actually took some getting used to coming from an old HD rear projection TV. It makes everything look more realistic and is kind of weird at first. The problem of course is finding 4K Ultra HD content to watch. Right now there don't appear to be any streaming devices capable of displaying 4K content. We've been able to see some using built in apps on the TV like Netflix and Youtube's 4K video selection but there isn't much. We'd already seen House of Cards season 2 but we're enjoying watching the Blacklist. Anyone else have 4K TV experiences to share?
