The biggest problems with the Xreals for me (I own an Air 2) on anything but their Beam and Beam Pro is the lack of any kind of 3D support and lack of developer support on Windows and macOS. So these end up being just a litera; 1920x1080 floating screen... which doesn't *quite* work since head movements will cause parts of the screen to vanish.
It's a nice 'one trick pony' and can be very useful if you need hands free computer use where the screen has to be in sight while not lugging the computer in front of you (think compact computers) or for passive movie watching or some types of gaming.
That comment about the iPod!, lol! They are pretty though. That laptop looks nice.
