Yeah I don't think it's great for the social TV watching. But plenty of people also watch TV solo, and play video games solo, etc.
The effect is pretty astounding in sports and video games, which might be enough to get away from the nerd stigma and maybe even make it a must have for some people.
I don't think it's a fad this time. This article didn't even cover the main attractions, which makes me think the author is either ignorant of the topic he's covering, or he's biased.
I'm personally not a huge pusher of 3d tv. In fact I'll probably wait until it's more mainstream and prices have dropped before I grab one. But yes, after seeing sports and video games in 3d at CES I will definitely get one eventually. Hopefully with more comfortable and less nerdy eyewear (just a matter of time before Oakley designs a set).
