I’m eyeing the x-real air 2 pro for a while, very curious how they would work

By default they just work like a 1080p display. It’s okay, but bounces with head movement, etc.

They work fairly well on Mac with their Nebula software, where you can have an extended display and control the distance if the screen and it accounts for head movements. The same software is not so great on PC, unfortunately.

On Linux, Wayne Heaney created Breezy Desktop, which is almost as good as Nebula, except for some stuff around the edges during movement[0]. He’s also created a very nice driver for the Steam Deck.

With a little bit of work you can also do 3D games and movies with them. Not quite easy enough for an elementary school kid, but not much worse.

What I’ve found is that I don’t use them around the house, but do while traveling. Not sure if that justifies the price. I’ve also got both versions of the Beam. Overall, I’d say it’s a push. When I’m traveling, I’m glad I have them. When I’m not traveling, I wonder why I have them.

I have one. I find it pretty bad for work. Low resolution, text is generally blurry and the corners of the screen are almost unusable with blurriness, colour aberration and other distortions.
