Current headsets resolution is already surprisingly good with some dev tricks. We use something called Compositor Layers at https://supermedium.com/ to render comic books in VR that look sharp and vivid. Not “retina” resolution yet but improving very quickly. Give it a couple of headset generations. We already have much much higher resolution and density panels but need to work within other constraints like small form factor, mobile SOCs limited compute power, weight, thermals and battery life.
It's still unclear to me what the benefit is, though. The drawbacks are obvious - I have to wear a headset, I lost the physical interfacing, both in terms of input interfaces and in terms of being able to, say, just a put an e-reader down to stop reading it. What do I gain, after giving up all that?
Best is to try. If you have an Oculus Quest handy you can give supermedium demo a try. Your feedback would be super appreciated. With a headset you get better ergonomics: resize and position a display at will and don’t have to hold anything. For comic books in particular, mural scale pages give you an appreciation of the art not possible on a traditional display. Notice that physical input is still available via controllers: similar to a TV remote or gamepad and also tracked in space enabling more subtle interactions than “traditional” input. Tracked physical keyboards will be eventually available too. I agree wearing / removing a headset is additional friction. We consider it a feature, not a bug. Hard to focus these days with so many distractions. Once you put a headset on you’re committed to the task and it removes all the noise. We see VR as a tool for focus, like shutting the door of a super fancy and private office.
