It's not a fad just no implementation has ever been ideal. I have and LG 3D Cinema display. Love it. I couldn't stand the Shutter glasses and just wanted the cheap polarized ones. Eventually glassless with few drawbacks will be here and everyone will bite.
I also have the Nvidia 3D Vision and I would say it's quite amazing but the cost is high due to the graphics horsepower required as well as 3D display costs.
I don't agree it's a gimmick but it's mostly for games vs. movies since movies converted to 3D are not so amazing. Playing any game in 3D even now is still always much funner than 2d and still makes me say WOW.
I would only buy a laptop with 3D if it had enough horsepower for games!
I feel that glasses-free 3D is the future, but as others have said, it needs to improve its visual quality versus using the parallax shutter glasses. The alternative is that they find out how to make glasses-free 3D cheap, but who knows how long that will take or if it will ever happen.
As to the question asked at the end of the article, 3D is here to stay. Though I understand those that see it as a fad and could agree with them in the here and now sense, but I think they are using a different definition of fad from the one implicitly suggested in the article.
3d on a laptop... really? And when they can't get battery life to stretch more than 2hours??? Seriously... I've purchased laptops that claim 5 to 8 hours. None have gone close to advertised and after about 6 months of use, the batteries usually half worn out. Don't give me BS features... give me better battery life.
I will be giving 3D (which I call stereo vision) all my thumbs up, but not my money till they bring me dual screen, actual dual screen, one for each eye, mounted in light enough glasses and usable in games with at least some compensation for head movement http://www.silver-brook.com/images/pup-tilted-head.jpg
And by then the screen will be curbed, spherical in fact (or appear so through careful manipulation with proper lens), with the same center as the eye, so no need for eye movement compensation.
That is when I will go stereo
