> Does anyone use their 3D glasses that used to ship with "3D TVs" circa 2013? My Samsung TV came with a pair of active 3D glasses that were collecting dust. On the other hand we've had adoption of touch screens on handheld devices, it almost swooped the entire mobile market between 2007-2012 after iPhone's introduction. But the same thing didn't happen with Keyboard + Mouse input on a desktop computer. Infact, the market just exploded with new mechanical keyboard aficionados sometime around 2010, I still remember hanging out on geekhack a decade ago and now mechanical keyboards are everywhere.
Glasses based 3D sucks. People who don't wear glasses don't want to wear glasses and find them unconfortable. People who do wear glasses don't want to wear two pairs of glasses and find it uncomfortable. Active shutter glasses give some people headaches from the flickering. If I could get perscription lenses with polarization for my TV's passive 3d, I might play with it... But I watched like one 3d blu-ray with the glasses and that's good enough for me. This display looks interesting because the viewer doesn't have to wear anything, but we'll see.
Touchscreens on mobile works because it's cheaper to build than a number pad, and way cheaper than a keyboard, it's cheaper to extend the touch screen so they don't use any real buttons on the front of most androids. The flexibility is helpful for text input.
A basic keyboard for a computer is $10 at retail because there is no size constraint making things expensive. Even a $10 keyboard has better user feedback than a touchscreen, but a computer sized touchscreen is going to cost more than $10. Plus, ergonomics. Touchpads could overtake mice, maybe, but desktop is being vastly overtaken by mobile, so it barely matters.

Consumers didn't flock to a more expensive phone (the iPhone in 2007) because it was cheaper to make (it wasn't). They did so because the touchscreen enabled new forms of interaction not yet possible, enabling full-screen games, photo viewing/shooting, and web browsing to name a few.
It was cheaper to make the iPhone with a touch screen, than it would have been to make it with a slide out keyboard. While the iPhone has a big market share in the US and a few other high income countries, touchscreen phones have taken over in almost all markets, even inexpensive phones, because they're cheaper to make, if you've already got a large enough screen and a fast enough processor in the phone for other reasons. You can still make a cost constrained phone where buttons is a better choice, but a cost constrained android isn't that much more expensive in absolute dollars, and provides so much more functionality so it only makes sense for the most cost constrained buyers, or those who eschew a smartphone for other reasons.
Biggest problem with TV 3D is the lack of content. If vast majority of content is not 3D, and the stuff that gets produced is usually done digitally and not through proper 3d cameras, it fizzles out as a gimmick.
This type of holographic display will have a similar issue, but it may be saved by the fact that it can be very impressive as a display in commercial uses.
Touchscreen just enabled another method of interacting with web and applications, method that was already present via use of mouses on PC. It did not depend on massive adoption by TV and movie industry with little benefit for them.
