A while back, in a discussion of the Sylvania Halolight, I asked rhetorically why, if it's such a good idea, no other manufacturers copied that feature.
Guess what -- Philips just did. We have one of their Ambilight sets with the backlighting. I wonder whether the halo light is actually an improvement.
