There are basically 2 groups of people
Group 1, the minority who when a technology is release can't understand why everyone doesn't want it and in a year or so when their unit is gathering dust they wonder why they bought it and are not surprised its discontinued.
Group 2, the majority, can't understand why anyone would want it, and just carry on with life.
3D TVs are an excellent example, so are Google glasses, Curved TVs will go the same way, so will smart TVs as Apple TV, Chromecast etc are far better value. Nintendo Wii, Blue-ray will probably go the same way, Betamax tapes, 8Track,etc etc etc. I suspect "The Cloud" will be here too as people realise they can do it at home + backup at a friends house, all securely encrypted is cheaper and more reliable.
There are somethings we will wonder how we did without in 10+ year time, 3d printing will be right up there
