One headset I’ve heard of that is aimed at more office focused usage is the SimulaVR[1]. However, it’s still a work in progress and you’d have to preorder.
Our headset boards were recently assembled, so we're expecting review units within days or weeks.[1] Our software is also demoable on GitHub for HTC Vive & Valve Index platforms.[2]
The screen(s) and mouse/kb aren't the current productivity bottleneck for people.
TLDR: they provide unlimited screens of any size, improve work focus & immersion, are usable outdoors (no laptop glare), improve privacy (no one around you can snoop your screen), and their compact design frees up desk space. They also promote better posture and freedom of movement: with a VR computer you can change positions, sit up, lean back, stand, lie down, or even walk while you compute.
