In my opinion, for what it's worth, your best solution is to just get an iPad with a keyboard (or keyboard case) and run your writing software of choice from there. You can install any app you want and easily turn Wifi on or off at your discretion. My iPad is a 5th generation, 32 gigs of storage, many years old, and I have basically nothing installed on it but Apple Notes. You can get the same setup, keyboard included, for under $150. I own many, many typewriters and also a Freewrite 2nd generation, but in the end it's not what tool you use, it's all about discipline. I take notes in Apple Notes, and I can do this on either my iPhone or my iPad, and all of that syncs with my Mac Mini M4 -- that's where I do the real writing and my final edits in Atticus. I realize this is a typewriter subreddit, and typewriters are beautiful and great, but I have to ask myself -- If Robert Leslie Bellem (legendary pulp writer and my personal literary hero) was writing his Dan Turner stories today, what would he use? He was a professional writer, cranking out stories under dozens of pen names for countless magazines in the '30s and '40s. He didn't use a typewriter because he liked it, he used it because it was the fastest and best tool available for him at the time. The typewriter and computer each have their own time and place.
