I can't lend any credence to the argument about leaking plasmas, because I have never seen one last longer than three years. "That's an awful lot of money to spend on a tv that only lasts a couple years."
My favorite question is, "What's the difference between HDTV and Plasma?" Very tough question to answer, I guess you could say, HDTVs don't leak.
I never drive faster than I can see, and besides that, its all in the reflexes.
