Every year or so I've been toying with the idea of a thin client dev environment. Smallest possible device that can run Linux (or a RDP client) and support being plugged in to a single USB-C dock cable (display, usb for keyboard/mouse and power).
Maybe this is the answer? Even though I don't need the screen, the footprint of a smartphone is smaller than almost all SBC supporting the above requirements.
