The original vision IIRC was to provide a cheap computer for students in low-income families. You could plug into your TV at home and start learning.
Then the hobby community got wind of it and proceeded to buy out all the stock on every release (myself included, I still have one of every first 3 versions sitting in my cabinet)
The concept of a cheap new computer like an RPi for poor families is a 1st world solution that doesn't understand markets. Used computers are way more popular in countries where the price of new computers are out of reach.
It's a supply chain problem, n
At this stage I think the way to realize this "cheap computer" vision is in unlocking smartphones. Either with an OS that behaves like a real computer that you can put on an old/cheap commodity phone, or with an app that creates a programmable environment layered over and isolated from the suffocating mobile OS.
