Plus,the resolution of Plasma TV's is way lower. You can see a clear 'Grain' on plasma TV's while you can't really see them on an LCD. (unless peering 5inch from the screen).
Plasma makes little sense. In order to not see the grain on Plasma TV's you need to put the Plasma screen further away. To put it away from you, the TV needs to increase in size, in order to have the same viewing comfort as with a similar LCD closer by.
Increase the TV,and you increase the powerdraw exponentially; meaning, putting a TV 2x further away, it'll need to grow 4x in size (2xlength, 2x width).
In the end you end up with needing a larger room, you see the same resolution, and use about 4 times the power of an LCD.
With the coming OLED TV's it makes little to no sense anymore to buy plasma. Oled has near to plasma contrast and brightness levels, and consumes even less than LCD.
Oled TV's also can come in 3-5mm thickness;about the size of a mirror with a stand. Way more attractive, way less powerconsumption, and viewing way intenser colors.
