I just got an Oculus Quest for my birthday a few weeks ago. This thing would be amazing on the plane! I am not even talking about games. There is an app call immersed VR and you could connect to your laptop and have multiple private big computer screens. You can even have a white board to write notes and walk around your virtual office.

And if you get bored working, you can watch a movie on like a 50' screen inside a movie theater using Bigscreen app. The Oculus Quest is really amazing for the price.. which is half of that of a premium smartphone.
