robbyp: I think LEDs have quitre a few advantages over plasma
I've not found many advantages of LCD/LED that relate to how the TV performs - ie how well it displays moving pictures / deals with the full brightness range from full black to full white.
Most benefits tend to be along the lines of:
It uses less power
It is lighter
It is thinner
These are all accurate, but how important are they?
It is hard to compare power accurately though as plasma consumption varies but LCD is fairly constant.
ie do you buy a TV to look at switched off, using no power that way, and light so you can move it around often easily?.....
