VR on a plane sounds interesting. But those headsets are pretty bulky right now, I wouldn't want to be juggling one along with food and everything else.

I'm surprised these AV systems haven't been replaced by cheap Android tablets - they'd be a hell of a lot cheaper and you could replace them very easily.

Many of those in-flight entertainment systems are Android tablets mounted onto the seatback. Sometimes if you're lucky you can bail out to the Android home screen on them.

On a recent Delta flight the seat back screens were malfunctioning and had to be rebooted several times. The boot was a standard Linux text mode sequence. Debian, iirc. It would get stuck before the graphical interface loaded.

Source? I doubt they would embed lithium batteries into the seats, and every device I've seen so far is powered on/off along with airplane systems.

You could both be an android tablet and run off a plug and not have a battery...

I would think nowadays they should be lightweight android tablets and a small 10 lbs media/wifi server box
