Vario XR has a very good resolution. Did anyone try to code with it?
It also doesn't actually have a particularly high resolution, and sort of cheats by making your periphery have a significantly lower resolution (hardware, not software, is responsible for this, so you can't just turn foveated rendering off), which makes it good for many use cases, but worse for programming.
Also, even disregarding the extra focal-spot screens, you're wrong about the resolution. It's the highest of all headsets that don't have insanely wide FOV's like the Pimax8K, by a long way. 2880 x 2720 per eye (Varjo VR-3) > 1832 x 1920 per eye (Quest 2) > 1440 x 1600 per eye (Vive Pro 2) ~= 1600 x 1440 per eye (Valve Index)

The TOS says that the minimum subscription length is 1 year, so that brings the absolute minimum cost to US$3990 for the VR-3.
