Citation needed. Chromebooks seem to be working for the edu sector.
They're also often exceptional deals for the low end of laptops (sub 200 dollar range) because Windows and its bloat make those laptops even worse to use. I'd never recommend any laptop that cheap unless someone has no meaningful way to save up, but this segment is very much still alive.
Honestly, I'm surprised the unification of smartphone and laptop hasn't reached those circles yet. A mid range phone and a cheap laptop shell that you can slide the phone into are a much better deal than a cheap laptop and a cheap phone. Samsung's DeX, for example, is fully competitive with ChromeOS and even most basic Windows use cases.
