Last month, we managed to get our hands on some 3-D glasses for a single commercial during the Super Bowl and NBC's "Chuck," but was kind of let down with the performance of the glasses. To be honest, we got kind of nauseous a few minutes in and couldn't wear them for the rest of the time during Chuck...
According to Gregory's experience at CES 2009, there are certain manufacturers such as Samsung that made attempts into the 3-D display category without the requirement of glasses. In the end, you did manage to see the images on the screen in 3-D, but only at 9 specific viewing angles.
Though impressive, just watching it for a minutes caused eye strain and became "a bit dizzying and disorienting." Not our idea of fun, especially if everything were to be in 3-D for hours on end.
Personally, I find multi-touch technology and holographic screens to be far more interesting than 3-D TV. Especially when it comes to increasing eye strain (something many of us already are experiencing without the "3-D" ingredient thrown in, anything that's even remotely aggravating to our vision should probably be avoided at all costs.
