If you're interested in running full Linux Desktop apps instead of Android apps, Simula is getting closer to releasing VR/AR compatible compute packs with laptop competitive specs: https://simulavr.com/blog/compute-pack-progress/
Reviews indicate the Steam Frame runs desktop Linux apps fairly well, too.
Oh wow, I didn't look at the price of the Xreal Aura, assuming it was something in the range of 399 to 599. Yeah, if it's the same price as the Steam Frame there's absolutely no contest.
I love example usage photos on this website, made me chuckle.
