Quest 3, the DPI looks somewhat similar to a non-retina Apple display.

It felt really futuristic to log into my office computer from a synthesized apartment via Virtual Desktop. The latency was fine for typing. Even YouTube video/audio was bearable. But the device itself is still too heavy. The fixed lens system can't be good for your eyes.

Apple Vision Pro is even heavier. Even as a hardcore VR fan I cannot imagine the current generation hardware to be useful in productivity tasks.

I attempted with the Quest 2 and it was far from doing the job well. Resolution is too low, optics too poor, headset too heavy and uncomfortable, battery too small. I’ve heard Quest 3 is better, but I am still very skeptical that the Vision Pro could be an all day device and replacement for a multi monitor setup. Possibly in a few years there will be a dedicated device for just virtual monitors designed for all day working. Xreal’s product is close but still very early adopter.

Not specific to the Quest, but potentially of use to some:

I've done it with a Valve Index and an HTC Vive Pro. I configured a virtual room with huge screens on the walls.

It worked OK. I wished the DPI was higher, but huge screens farther away from my head worked well enough to use Visual Studio, etc.

The issue I had was eye strain and headaches. This was with snap-in vision correcting lenses for the Vive Pro.

I could do a full 8 hour day, but had a low-key headache and dry eyes the rest of the day.

Used one myself with Immersed, I’m a single screen guy so it wasn’t worth it for me. Works pretty well though no major complaints.
