Too complicated I helped my friend set up his new smart TV and all he had to do was enter the key for the WiFi. It took him about a year to figure it out. He still doesn't use it. His Blu-ray player has all of the same functions. Also, a lot of the content requires extra payments. You'd presume that some of that was included in the price of the more expensive networked device...
My Blu-ray player was connected, but I never used the features. Too limited. HTPC kicks buttocks by comparison.
I'm hoping 3DTV just fades away again. No interest.
