Maybe some bored flier has been using it to try to install a Linux kernel into the Thales system. Then they'll offer up here a full fledged Linux desktop on the screen with seat-to-seat gaming, onboard Twitter feeds, movie file sharing from your laptop, etc....

Flight after flight, USB flash drive, wait for FA to reboot system, bring up the kernel, capture diagnostics, wait for next flight....

When you gotta do 100,000 miles a year, you have to do something to keep your mind engaged....
