I do appreciate that! It just seems seriously counter-intuitive to claim that spending 600W to put a moving colour picture on a screen the size of a bed-pillow

I do appreciate that! It just seems seriously counter-intuitive to claim that spending 600W to put a moving colour picture on a screen the size of a bed-pillow counts as "efficient". [Edit: obviously it doesn't take 600W to play back an HD movie - the energy is being spent on game computations, or hashing, or something like that]
