I spent much of last evening on a plane. My laptop, a Dell M11x, didn't have an adapter that worked with the American Airlines cigarette lighter plug, so I had to use the laptop battery, which meant my screen was really dim as I tried to preserve my system's precious juice. This is one of the reasons I'm flying Virgin America now: They not only have Wi-Fi (which American increasingly has as well) they have normal US AC pugs. Hey there's an idea, let's put power on planes that I can actually plug into! Those tricky Europeans.
