I've seen a couple of plasma units (in the $14000 range) in stores and I'm really surprised at the, to me, ordinary looking picture quality. They seem like simply wide Sony tube TV's...nothing like the sharpness and smoothness available on a rear projection TV of similar size screen. The units were driven by DVDs, so it can't be a bad cable TV feed or something. What gives? Are plasma superior to RPJ TVs, and if so why can't I see it?
