That’s basically what I got. Xreal Air (formerly Nreal until a C&D from Epic). 1080p per eye and something like 49PPD with a 45° FOV. Tracking is 6DOF and requires software on the host (only complaint) and connectivity is via a USB-C cable (uses DP alt mode).
It’s nearly as “dumb” as an HMD can get. From the teardowns that I’ve seen, it’s really just got an MCU, a GPIO expander, a 6DOF chip, and the displays + drivers. And I love that about it. No batteries or anything to worry about.
