This or any tiling window manager, because small screen. If dwm is hard for you, try with bellow options.
i3wm was my first, but now I’m happy with my actual dwm config.

I usually use Lemmy at my smartphone with 4G that was released 3 years ago, I’m happy with it, and I don’t need other one more new and expensive.

Today’s web is very bloated for no reason, and very slow in old computers. Browsers are the main RAM eaters.
