I'm not into curved TVs, I think it's nuts that we spent ALL this time getting our screens flat, to just curve them the other way. The only time a screen HAS to be curved is if it will fill your entire range of vision (like a gaming chair, big monitor, or a giant cinema screen). Also, I believe the image has to be cut or distorted for the curve to work, if you watch movies on the big big big screen, you'll notice parts at the top and bottom being cut off.
But for most people, the curved TV will just replace the flat TV on their walls and stick out, they won't be used to their maximum effectiveness, I think, because the people rich enough to afford them are also smart/old enough to sit far away from the screen to avoid eyestrain.
