For me, the problem is that if I don't see it, it doesn't exist. Slack, server monitoring, other communications channels, they all take up real estate. My daily driver is a 43" 4K monitor. Basically 4x 24" 1080p monitors in one. It's the exact opposite of portable.

I can get any task done with my laptop. But not a full day's work. And if I want to travel while I work (which I would like to do) then I need a better solution. This is why I'm looking into VR and also a 4K projector, but a projector would have to be able to be seen in a bright environment, and I don't know what the current state of projectors is.
