Its always about the buzzwords... a few years ago I tried to buy a TV without 3D-support because I didn´t want to spend the money on a useless feature (for me). Guess what, no major brand offered a TV without 3D, I ended up buying the usual suspect. But now the situation has improved ! It got easy again to buy a TV without 3D-support at least :D
Same for the current must-have features...
I think the common nerd would love a dumb display with decent calibration etc. out-of-the-box, so he could just connect his favorite media-box and have fun for a reasonable price. But this isn´t where the profits are made!
edit: Because you could just replace your mediabox after a few years, when e.g. netflix stops playing on it. I´m really waiting for a new player who gives us this dumb high-quality display so many nerds are waiting for.
