The issue of display is the only thing that keeps me dragging a laptop around. I've been keeping an eye on monitor replacement AR glasses but looks like I'll be waiting another decade or so for anything consumer ready.
I have an ASUS Zenscreen MB16A. It's very portable, has a battery, touchscreen, speakers, input from either micro HDMI or USB C. The only disadvantage is that the battery will only last a few hours unless you have it plugged into usb-c charger, and I haven't worked out a way of charging it and giving it a usb-c signal at the same time yet (so when I'm using it at my desk I use the micro HDMI input).
