That weird Ambilight FlatTV by Philips got an upgrade at CES this year. If you didn't already know, Ambilight technology basically uses ambient light around the screen of the TV to match what you're watching. So it's a backlight system that you can customize, to create "a deeper, more immersive viewing environment." Right. So this year, the new Ambilight FlatTV comes in Full Surround, which seems to mean a four-sided model, with sizes ranging from 37 to 50 inches. The Full Surround uses lighting on all sides of the TV—and is liberally being called "surround-sight." Prices start at $2299 and go to $3999. Hallucinogenic drugs not included.
