Most of the tech which has fascinated me over the years DIDN'T flop, so I have little to say on this thread... with ONE exception: 3D Shutter Glasses.
Back in 2001, Mom and I had a computer built under the distinct notion that I would be taking it with me if and when I finally moved out into the world on my own (which I did in mid-2002), so I was picking a lot of components which made the most sense to me. One of the ones I picked for a GPU was a GeForce 2 card that came with 3D shutter glasses, and we had also picked out a 120 Hz 17" flat CRT (though I quickly found out that 120 Hz could only work up to 640x480, then the maximum Hz steadily dropped off down to 60 Hz at 1280x1024). Not only did I find the notion of having shutter glasses cool, but the card was also very decently priced so I figured why not?
As a result of experiencing 3D in gaming so early in life, it came as no surprise to me that the modern 3D gimmick with TVs didn't really catch on. The experience itself is fun, it's just when 3D requires you to do something inconvenient to experience it, it cannot ever leave the realm of gimmicky because it becomes an inconvenience to use the feature, thus people stop using it. Indeed, I ultimately did stop using my shutter glasses when I realized just how hard it made it to see certain things or even just to aim weapons in a game, not to mention having to play at lower resolutions to avoid severe flickering.
I'll still go to see the occasional movie in 3D, but only because I'm with someone else who wants to see it that way, or because the non-3D options are at inconvenient times. It gets worse with 3D TV because the glasses are usually wireless and thus have to be charged when not in use. The 3DS ALMOST managed to bring 3D out of the gimmicky realm, but because you'd have to hold it in a particular way to see the effect, and because it ran the batteries down faster, it again stayed as a gimmick. (And I do mean JUST the 3D effect, not the 3DS as a whole.)
...speaking of, I've still never used a 3DS in person yet... I do intend to get one someday...
