I'm curious if anyone will be able to develop in it (i.e. write code with virtual desktops etc) I'm also curious about how which unexpected consequences people will experience with such devices (nausea, etc... other unknown illnesses cropping up)
If it's comfortable enough to wear for prolonged of times it might be superior to most common multi monitor setups that users have these days. Nausea would be induced by lack of visual references and latency issues. AR with good responsiveness should address that. Eye fatigue and headaches might be another issue. Too early to tell but this might not be that much of an issue. Otherwise, it looks all good.
At least this way, I could actually do stretches and exercises while watching some video.
Even prolonged usage of a smartphone is painful. So is prolonged usage of any computing device.
