Earbud screen reader with a one-handed chorded keyboard, privately, aurally jacks you in with fully control and access to the entirety of the interoperable gopheric www.
Think about it... the fediverse streamed as a constant, steady machine read babble tapped into your inner ear. & in the other: a drone of your curated infotainment RSS feed - cut-up and filtered into an incremental reading battery to append to your ANKI spaced repetition review.
Wikipedia can be referenced, dictionaries and thesauruses recalled, 4chan lurked, notes taken, code written, your main machine ssh’d: anywhere, spontaneously, surreptitiously - with no interactive facility occupied beyond a single ear and single hand, and no worn hardware necessary beyond a basic set of earbuds, a pocket computer and whatever controller pad.

is kind of small for that imo, but maybe. you can run alpine linux on one of these. obv with the zerophone you don't have a normal display. if you intend to pair it with some kind of control surface it might even make sense to omit most of the buttons on the device.
i'd just use like a special REPL for that kind of thing. since you aren't going to be looking at it, all you really want is a text buffer.
