Leaving aside developing countries for a moment; I know, personally, multiple game developers who have switched to using RPi4 and Pinebooks as their personal computing devices.

They hit this sweet spot of just enough power to be useful, yet totally silent (with a Flirc case on the Pi).

The RPi3b just wasn't quite there yet in terms of speed, but the 4 can easily drive dual monitors and provide enough oompf to be useful in a game jam. Quite a nice little device for hobby development.
