I'm using 4k 50" from Seiki as my monitor and it is awsome (never going back.) The only problem is that at the distance of <4 feet from it the corners are at less than optimal angle and curved TVs will help with that. So I say that it might be a gimmick in the TV market but definitely not if you use it as a computer monitor, like I do. In fact I plan to buy Samsung 55" in next few months.
