Did you buy it for the "smart" features, or did the TV that had the resolution etc. you wanted just happen to have smart features? I get why average consumers buy smart TVs but I would have expected you (and most other people on this site) to stick a general purpose computer behind the TV and use that instead with some media centre software like kodi - so much easier to update and tinker with. If an update goes wrong with your TV you could end up with a shiny brick, which is a rather strong incentive against developing for it! Or did you buy it to try Tizen? Just curious!
