MiniPCs, portable monitors?

Hello, it’s midnight where I am and I fell into a rabbit hole of MiniPCs and portable monitors.

I work from home with the occasional max once a month summon to office. I travel a lot and I ended up wondering if a MiniPC like Geekom would be for me.

I currently have a ThinkPad but I have an external keyboard, mouse, monitor, speaker and webcam at home. I only ever use the actual laptop parts when I am on a train or traveling. Which is also a pity because the laptop is heavy for me.

Anyway, does anyone travel with a MiniPC / monitor combo? I would love to hear your experiences and advice and maybe some obvious and not-so-obvious pros and cons that you can share.
