A personal theory of mine is that one reason telecommuting is hard is that is really screen-real-estate bound. I've been remote for 5 years, full time, and in that time I have come to rely on an iPad Pro, 2 laptops and 2 30 inch 4k monitors, all on all the time. I'm on the phone maybe 4 hours a day, sometimes up to 8. (I don't work in coding, FWIW). I have so many documents, projects, collaboration windows, schedules, emails, calendars, and checklists open all the time that it is easily more productive to add more screens.
One thing I have learned is that collaboration and individual productivity are kind of opposing forces. To do one well, I do the other poorly. As a result I split my time between them (I manage a team, so I try to push for more collaboration so that they can work efficiently more of the time). When I am working solo, I prefer the untethered laptop with one screen. When I am collaborating, I would gladly double what I have now.
I say this because I can see a day in (in my mind's eye), when I have augmented reality glasses that provide infinite, location/object-fixed screen real estate around my house and office that I can use to collaborate better, and then simply set aside when I don't need it. I really want to be free to have the room around me be a canvas on which to work and collaborate. I'm interested in VR, but I prefer the experience of the AR solutions I have seen so far since I don't need to contend as much with focus and motion sickness.
