I recently travelled and needed to work (coding and video editing in DaVinci) a lot in hotels and random places. I can't bring large screens everywhere (and I hate to work with small fonts and screens), and Quest 3 was a perfect fit here. Sometimes at home or office (I have a private one), I just don't want to sit on my buttoks all the time, so I put on VR goggles and can keep working in any position (lying on a sofa or even sunbathing outdoors).
As soon as new XR/MR glasses become lighter (there are some good ones already - Visor, Beyond BigScreen 2, etc), more and more people will discover how usable and optimized for work this tech is.
