I still have one of the Oculus Devkits at home from their initial campaign. It's more than 10 years old now. I've noticed the biggest improvements to VR over the last decade were in useability - not the screen. Once they figured out low latency by switching the screen to black after every frame every device upgrade felt like a tiny improvement in resolution at best. Size 12 font text on a 2m screen wasn't really readable yet, but I still don't use VR for text work today (even though I could) so it also doesn't matter. Right now it's still a question of usability rather than the screen.
