I was listening to a podcast interview with the head of Panasonic's
flatscreen TV division and he dismissed both the concerns about burnin
and lifetime for plasmas. I'll have to dig up the other review I was
reading where they talked about burn-in as well.
http://www.itconversations.com/shows/detail562.html is the link to the
interview. The guy sounded pretty knowledgeable.
