Speaking of the Philips Cinema 21:9, Scott Simmons of Editblog fame has a post concerning, to put it bluntly, the bullshit of "picture enhancing features" on new TVs, specifically, Philps.  This sums up his feelings (and mine):

I call marketing bullshit on this TV.

I couldn't have said it better. And I won't. Go read Scott's take on features like Ambilight, "Perfect Natural Motion," and "distortion free" picture resizing. The general consensus is that none of it adds to the viewing experience in a positive way.
