Re: "VR for working on a plane" - you could look into XR glasses like the ones from XReal or Viture.
I've been considering a pair for myself after hearing good feedback from some friends, and seeing some good reviews online.
The latest versions have head tracking so the virtual screen remains "pinned" in your view.
They're also much smaller and easier to carry compared to a full VR headset, and they can plug into almost any device (laptop, tablet, phone) and just show up as an external monitor.
I’ve been tempted, but a lot of the forum feedback (ie not the breathless YouTube “reviews”), suggest that optically they are pretty bad, especially near the edges.
The xReal ones are extremely workable. Like, you wouldn't want to do it by preference if a good monitor was available, but easily good enough for a situation where you don't want to use a monitor or don't have one.
I also have the Viture Pros. They are awesome for airplane/hotel use. Not great as second monitors, as you say optically they aren't perfect and text makes that show a bit more... but if you hook up a steamdeck or want to watch Netflix on the go it's great!
Don't get me wrong, they work as a monitor in a pinch on a plane when you need privacy it's just not going to ever replace a real monitor for you.
