That's why I got an XPS 13. My old 13.3" was borderline too large, and 15" definitely too big for a plane. Trade-off as you get older is a 13" screen is kind of small.
Clients don't always have the resources I'd like, so that's why I'm looking for something like a 15" portable monitor. Pretty much always end-up working off a laptop - forgot how nice an actual desktop spread out is. I did get myself a wireless mouse a few years ago, which was like "why was I too stupid to do this sooner?".
Embarrassingly, I still haven't done that. I usually try to stay on top of advancing tech in tools, but one thing I've carried with me for over a decade now is my stupid trackball mouse. I've gotten used to using the trackball with my index finger as opposed to thumb, which most seem to be built for now. It's the one little area where I fall back to being a creature of habit.
You're absolutely right, though, about being able to spread out a bit. For my last trip to San Francisco, even though I was still using a laptop at the time, I lugged my mouse, keyboard, and a USB cable with me, and I hooked up to a television while I was there. I just can't get comfortable working in such a small space anymore.
That, and my home setup has always been a little spoiling. About four years ago, I won a 4K 40" television at a Christmas party. Since our television in the living room was already bigger, and almost none of what we watch is 4K anyway, I've been using it as my monitor. Between that, the robust keyboard, my old-ass (but favorite) mouse, a decent machine, and a big whiteboard on my wall, I have a better setup in my home office than I've ever had in any office I used at an actual workplace.
This last month, we had an on-location FFL draft in Indiana. I brought the giant monitor and keyboard, because it was what I had. The smaller one and a portable screen would have been a MUCH better choice ... and I would have gotten far less ribbing from the other managers for it. lol
