3D: The panacea no one wants

January 13, 2011 12:22 pm | by Jason Lomberg, Technical Editor | Comments

To paraphrase David Farragut, damn the sales figures; full speed ahead! If CES 2011 signaled anything, it was the industry’s intent on shoving 3D down our throats. The most vocal proponent, Sony, claims they’ll “lead the industry’s charge for 3D.” Yet for the industry, it’s more like a holy crusade.
