It's only dumb if a significant portion of their customer base feels that way. I don't know the answer to that issue (I only know that I used 3D a couple times on the F9000 and none on the JS9500). However, I'll bet that Samsung sampled the issue and believes including 3D isn't cost effective.Well that's dumb. Stereoscopic 3D is awesome and I use it on my Samsung all the time, from hundreds of hours worth of 3D Blu-rays to most PC games I play, I play in 3D. It is a killer app and I wouldn't have bought the TV if it didn't have it. I'd rather watch a 1080p 3D movie than a 4K 2D one.
