There is a lot of science behind the curve, it's not just for coolness. I have a curved TV myself.
The corners of the screen on a curvered TV is the same distance away from your eye as the center of the screen. On a regular flat TV, your eyes will go in and out of focus slightly depending on where you're looking. A curved TV alleviates this for a more comfortable viewing experience. Eventually, all TVs and Monitors will be curvered.
