Samsung has one of these that is as big as a living room window.
Cool, but whatever it costs, it costs a lot. So make your own:
The big one is insanely cool, with touch screen capability, the ability to go completely dark, and a day/night option (backlight). I'd embed it, but the geniuses who run CNN Money's marketing group have embedding disabled. And so what is a fabulous interview and demo has 166 views. Awesome marketing.
