Seven years ago, I landed a fairly trivial job with a temp agency, and we were tasked with plowing through document archives and collating them all for the scanning team. Our client was a huge company, and though none of us were sworn to secrecy or anything formal, I figured I would do them a solid, and refrain from bringing in any device with a camera, microphone, or transmitter. At the time, this was possible because I didn't rely 100% on my smartphone for transportation and everything else... So I delved into the fascinating and still-extant world of standalone MP3 players. I selected a SanDisk Clip Jam, and it had like 8GiB onboard, an sdcard slot of course, an FM radio receiver, and really cool firmware. It was very simple, robust, extremely light, compact and portable. It was the size of a matchbox and it could clip onto your sleeve or belt, or whatever. And it met all the requirements. It had no BT, no WiFi, no sensors of any kind, and it did that job very well of music playback, however I found it. And it could indeed store arbitrary files, so being the kind of hacker I am, I stashed a copy of my password manager encrypted database, plus a full install MSI of the application. And I included some README.txt that would indicate who owned this thing and how to return it, if lost. I really miss that thing for its elegant simplicity. With the Swiss Army Knife nature of smartphones, I still long for the specialization and compartmented functionality of separate devices.
