On Virgin America’s new planes you can build a private playlist from the 3,000 on-board MP3s, play Doom, watch satellite TV, chat with other passengers or order lunch, all from the seat back in front of you. The computers that make this possible run Linux, booted over the network from one of the three servers at the back of the plane. Artur Bergman of O’Reilly Radar has a more detailed description of the experience, and a Flickr photoset with a bunch of cool pics.
