There's no way that guy can't afford $50 for a used laptop.

He doesn't appear to say that he can't either - it's just a screenshot of termux. Guess what? I've also taken screenshots of termux. It's neat. If all you have is your phone or tablet, it works.

On his twitter page the only thing I see is a screenshot of gnome-terminal. So I guess he can indeed afford it.
