Want even more reason why Virgin America should be approved by the Department of Transportation? Take a look at this video that focuses on the seat-back entertainment on each seat. The screens are 9-inch and touchscreen, which are powered by an actual individual PC running Linux. These are all interconnected via Ethernet, which grab streaming video off of three file servers in the plane's belly. You can listen to music, watch TV, get pay-per-view movies, or even order food from the touchscreen. The best part? They ported a bunch of Linux games-including Doom- so you can play it right on the screen.
