They suffer the same issues as other VR solutions (focusing on fine text can be hard, it shakes on your head, etc). But unlike the Quest, you can set it to “Aircast” mode which basically replaces an VR/AR experience and turns the headset into a true “head mounted monitor” - which is different than their special software. I tried it with their virtual monitor software, and it’s unusable. If you move your head, it refreshes the monitor you’re viewing at like 2fps so it’s super jerky and not smooth.
It’s not good enough to replace a real stationary monitor for me yet, but it’s probably good enough for someone constantly on the go, or for airplane usage (extra privacy). They’re also far more comfortable than a Quest since they don’t have batteries or a processor built in.
I want to add that I think they shake more than the quest because you can’t strap it in tightly like you can with a quest and a hard strap
