How about everyone taking a long flight or just staying at a hotel etc?

That IMO is where VR glasses are actually a pretty good fit. Carry lightweight laptop through the airport and still get to use a 32” monitor on the go. Granted the current hardware not exactly ideal, but it’s close enough to be a reasonable option.

Don't underestimate the unwieldy shape of these headsets, they aren't very bag-friendly. The Apple design seems to do some compromises to decrease bulk but it still won't nicely slip between other stuff. Portable displays on the other hand, they are wildly underappreciated because so many still haven't the slightest idea that product category exists. They offer a very favorable bulk/utility trade-off and allow day on day scaling between the extremes of the smallest laptop you can find and what could be considered a mobile workstation.

These devices are currently bulky, but you can easily but them and a a bunch of other stuff into an under seat airline bag. The weight and volume is annoying but not a dealbreaker.

Also, I think we can all agree the form factor is likely to improve over time. Portable displays meanwhile have inherent limitations in use ie an airline seat.
