I've been doing this for nearly five years now, so I've gradually built up a system that works for me. Usually I'll use one of two devices:

* Asus Chromebook Flip (C100PA)

* iPad Pro 10.5 with keyboard cover

When I'm developing, I use ssh or mosh to access my workstation in the office and then tmux+vim. Mosh works pretty great with poor connectivity. I've pretty much mentally mapped the signal quality along my route, so I know when to look out the window for a couple of minutes to wait for signal to come back...

When I'm not developing, I'm usually using Gmail+Google Docs/Sheets/etc to get stuff done. They all work relatively well offline/online.

For connectivity, I use a Raspberry Pi Zero with a 4G data stick as a WiFi hotspot (the on-train WiFi is terrible, and tethering to my phone kills the phone battery way too quickly). That setup can run for 6-8 hours on a little Anker USB battery pack.

You are an hero for using Raspberry PI Zero with 4G data stick. Applauses. How do you power it? Battery or plug?

Why not use a usb battery pack for your phone? Seems like one fewer thing to carry, and no extra 4G cellular contract.

This generally seems to be my conclusion when thinking about making something cool with a Pi or similar, wondering if I’m missing something?

It's a fascinating idea. The Pi Zero is tiny (likely much smaller than the battery pack). I'd think it's not that big a deal. Plus, depending on your employer, they may have unreasonable requirements for subsidizing a phone contract vs a 4G stick.
