In my case, I've got a random 30 eur (~$25?) Chinese netbook over Ali-whatever with Android and 1GB. Totally outdated specs, but with Fdroid (huge repo off libre apps) and Termux (tmux, Perl, clang, lynx...LOTS of CLI libre tools) it makes an amazing machine for the price of two hard-cover books.
EDIT: mocp under Termux works, so is not as limited as I tought.
