Toshiba's got a thing for glasses-free 3D displays and that it's been putting together 3D concept laptops based on the technology, but according to Toshiba's director of product marketing Phil Osako, the company could be ready to bring a 3D laptop sans spectacles to market by the end of the year. Sounds good to us, but it's a pretty ambitious claim, considering the demo unit Toshiba's bringing to CES, which we got to see a few weeks ago, is very rough around the edges. As you can see in the images below, it had a very large red, chiseled contraption strapped to its lid -- although, we do have to say it gives it a rather Iron Man-esq aesthetic. All that aside, the Qosmio laptop packs some pretty innovative 3D technologies -- not only does it have two parallax 3D LCD, but its webcam has a special eye-tracking feature that knows when you shift your position. The goal of that is to provide "dead-zone free stereoscopic 3D images" or better viewing angles, but we can't really say we experienced that -- while the 3D clips looked, well three-dee straight on, slightly tilting to the left or right threw off the effect and we were stuck watching some blurry content. Like we said, the concept is really just a concept at this point, but it will certainly be interesting to watch what Toshiba is able to improve and put out by the end of 2011.
