I just use whatever laptop/tablet-type thing I have at the time.

My proper desk set up is just so much better than anything portable (not just keyboard, but also monitors, trackball, lighting, etc.) that it's not really worth doing any "real" work on the go - so while I have a number of portable devices, they're effectively just for doing stuff that can't reasonably wait until back at my desk.

(For that matter, I've effectively ditched all of my "work-capable" portable devices - my largest-screen portable devices are a Chromebook and a 13" cell-connected iPad w/ Magic Keyboard. They're both very capable devices in their own rights, but I'm not going to try to do <day job work> on them.)

I travel with my Ferris Sweep, 2.5" drive travel case is a perfect fit.

If you don't mind looking like a blade runner extra who's gone missing while working in public, there's not much difference carrying these around. The moonlander is a great portable option. Just slip it in your laptop bag.

I quite like it because it gives me a bit of flexibility on where I put them, and gives me a bit of extra room in the middle. Great for a small airport table or whatever, can even use them rested on your legs

I appreciate all the earnest feedback to my tongue-in-cheek comment! I’m really tempted to try one out

No, some are very portable. I use a Totem which is a 38 key split. It's very compact and fits into a small case I could easily just carry by hand if I wanted to.
