I spent around 3300$(converted to $) a few years ago on a so called "smart TV" from Samsung. Less than a year after I bought it, they stopped updating the software. They never fixed it's problems with remember subtitles settings.
The "Smart TV" part never got to be in any usable state and now after Netflix has entered my country, it is clear that this model will never get a downloadable app for Netflix.
So, no, I am not going to spend YET more money on a new TV when it is capable of showing a picture. Although I would have liked to have a all-in-one box, I guess it is not possible so I still have to buy boxes and then still use the tv as a monitor.
