I'm currently sitting in the Star Alliance lounge at Heathrow. This is the first time I've flown international first class, and lemme tell you... I could get spoiled by it. I have wifi, a comfy lounge, and an array of food and drink at my disposal including enough beer and liquor to make an ADB plead for mercy.
What I don't have, however, is an ethernet cable. I could not find one for sale anywhere in the departure lounge-- the only store that carries them was sold out. Why do I care? I have internet access on the Frankfurt to San Francisco leg of the trip. Could you resist twittering from over Greenland?
