Not only because of the resolution, but also it’s tiring to have something strapped to your face, and it makes it hard to have a cup of coffee or a snack.
You seem to have a setup that works for you for productivity tasks, so please share!
It was best curved and large (and angled down a bit) so that I use it like it is 4 1080p screens. And move head to see each (and a bit more) sharp.
The newer version (tested briefly) lets you arrange several virtual monitors wherever. Not as convenient/sharp as a large 4k tv/monitor on my desk, but for a backup monitor and mobile it was great. I’ll give it a shot again.
(I can even work remotely if both sides have very fast broadband)
One caveat - this is an alternative to using a laptop and my eyesight is somewhat flawed due to middle age. If you're a 20-something with perfect vision and an addiction to 4k screens then this is probably a step down. For me it's on par with my non-VR experience.
