American Airlines has debuted in-flight Wi-Fi from Aircell, giving more aspiring business-class passengers the chance to look busy on their laptops. The service bans Skype and other VOIP phone services. The only people really complaining that you can't make Internet phone calls are tech-blog commenters — exactly the kind of people who can't be trusted to not shout into their new phones in the first place. Why doesn't American just ban them? That seems easier.
