Think people with chromebooks or old laptops who cannot use it for development. Or restricted laptops loaned from school which do not allow anyone but admin access to install anything.

I agree. I think it's great. I was trying to point out that most(?) Android and iOS devices allow you to connect any cheap USB or Bluetooth keyboard.

My MacBook Pro died from humidity while I was trapped in the amazon rainforest during the panedemic, and I had to do some work, so I bought an USB keyboard in Iquitos and I set up a development environment with postgres, vim, tmux, ruby, rails etc, inside Termux. Small screen, and no devtools in mobile browsers, but worked pretty good otherwise.
