Physically it doesn’t work:
The headset is too clunky and heavy still, after a few hours you get a sore neck and I have trouble with lack of airflow on my skin (where it contacts my face gets sweaty and irritated after long periods)
More importantly: the resolution is too small. Using an IDE to edit text inside VR technically works, but the font size has to be so huge because the resolution inside is so poor, coding becomes an exercise in scrolling and navigation rather than an exercise in problem solving.
I’m the same as you, I like being portable, and when I was a travelling tech nomad for 2 years it meant hauling two monitors in the car everywhere.
One other option that actually worked well was getting a good quality 1080p projector and mounting it on a camera stand, I used this for a bit instead of monitors at the hotels/Airbnbs and it worked well, although that’s just a single 1080p monitor
