yeah...a lcd will last longer...
but a plasma is my piece of choice for sure.
i got a panasonic 46 inch plasma tv and this thing rocks!
you've never seen that much precise colors in a tv and with a lcd you will never see ;)
if you want something that doesn't take too much electrical power...and if you want something that lasts two or three years longer, then go and get a lcd.
but if you want the real world in your tv...real colors, accurate timing and just a great picture...then check out a panasonic or pioneer plasma tv.
