Laptop screens I find are way too small. I have yet to see someone willingly choose a 15″ monitor for their desktop computer! There are powerful small form factor computers out there, whether the M1 Mac Mini or PC’s. And there are compact keyboards. The problem is the monitor we want to use. I could carry a 24″ or even a 27″ easily in a large bag. The problem is that stand that is so often awkwardly shaped. We need a collapsing stand, something that folds flat. I seem to recall IBM offering this in an old monitor so maybe its offered today. If the stand has a VESA mounting style (4 x 100 mm spacing) then you can get the right stand and use it with any monitor that also has VESA mounting and many do. The only other issue would be lighting if you do video calls but maybe a LED flashlight behind the camera with a diffuser would suffice and most people travel with a LED flashlight already. Of course the downside to this style of computer is its rather difficult
to use when in transit. Go to the bathroom and someone can steal
everything! So get a tablet for in transit use I guess or limp along
with your phone.
