In a nutshell, what's the difference between a TH-42PWD5UY and a TH-42PW5B? On the face of it they have the same resolution, same input spec and so on but one's finished in silver and the other black, and you can expect to pay more for the 5B. What's all that about, then? Perhaps it has something to do with the manufacturer's distinction between plasmas for commercial use and plasmas for domestic use. Don't really understand that either.
