I bought it ages ago, thought I needed it more than I did. The devs deserved support at the time, however....
Every interaction I've seen with them on their own forums since then hasn't painted a good picture of themselves. They can be quite arsey with people.
They never developed a Samsung app and left the 3rd party guy to fend for himself against hordes of users giving him grief for broken/lack-of features.
They did develop an LG app which made me a very happy bunny, but it turned out to be one of the worst media players I've ever used. The audio does not get translated correctly at all. The alternative was to use another 3rd party guy's app, except he charges almost a tenner for it and the whole experience is not a patch on the Samsung guy's.
One of the main benefits is it tracking what you've watched. You can't get this if you hop between accounts.
