If the power usage really is anywhere near as high as the graph says -- 30 to 45 watts range -- then the laptops aren't going to get much battery life. That is a lot of power to be using. I suspect that they were testing on the plugged into wall socket power profile, where speed is the main concern, and not power usage. Power consumption changes when the laptop is running off of battery. Edit: My X200 Tablet runs at about 12 watts on Linux right now, on battery.
