Yep, curved TV's are now being brought to market:

QuoteBut I think being curved is a good way of pushing the OLED technology to consumers and acting as a marketing tool.

I've only seen OLED screens on small devices (4"-17"). This, although $13k, is getting there on size. An LCD, LED backlit screen is nearer $1-2k though.
