Assuming that is the same TV I read about a couple days ago (I'm not completely sure, but I assume it is) you can't sit just anywhere for it to work. The article I saw said you had to sit about +/- 40 degrees from straight it front of it, and at a certain distance away. It's certainly a step up from the 3D that requires glasses, but it's not far enough that I would be willing to pay that much for it.
The two biggest problems I see with 3D right now is 1. the glasses, and 2. the price. I wear regular glasses, so wearing additional ones on top of them isn't exactly fun. Ironically, the cheap ones they give you at movie theaters are actually better for me than the $120 fancy ones, because they're so oversized that I can (relativley) comfortably put them on over my glasses.
The price I'm sure will come down eventually, but right now it's just way too much. $1000+ for the TV, $100+ for each pair of glasses (that I can't even use), plus you need to buy the console that plays those games (PS3 at the moment for $300). That is a ridiculous amount to pay for something that arguably had no effect on gameplay.
Nintendo has the right idea with the 3DS; no glasses and it's affordable. They still haven't announced the price for anywhere outside of Japan yet, but since the Japanese price is about $300, it won't be anything more than that. I'm guessing it will sell for $250. Either way it is much better than anything else out there.
I don't typically wait in line to get anything, games or consoles, on release day, but I'm making an exception for the 3DS. I don't think I've ever been so excited about a new console release. I don't want it specifically for the 3D, though. It looks like it will have an amazing starting lineup of games, plus a ton of awesome new features. 3D is just the icing on the cake. Unless I am horribly off on my guess of the price, come March 2011 I'm camping out in front of Best Buy or whatever to get my hands on one.
