I got a Raspberry Pi 3B+, and it mostly sat here doing nothing.
I found a Linux distribution called F123 [1], and installed it.
The distribution is designed for blind people, so all the accessibility components just worked. This was a change from having to get things going yourself years ago when I tried this.

Orca seems a bit slow in Pluma while writing this post. It can't keep up with my typing at all, and is a few words behind when it echoes by word.

A GUI on a machine like the Pi shouldn't be this slow, so it must be caused by the accessibility stack.
I was editing just fine years ago on machines much less powerful than this.
While I could use a terminal editor, most of them don't have the accessibility of their GUI counterparts.
Especially with long lines and scrolling.

If I run Firefox, and browse to a complex site, I can't interact with anything else while it's loading because I assume orca is busy processing events.
It took me several minutes to read one Reddit post, because of how slow Firefox was, and I couldn't do anything else while it was loading. This is a common problem with screen readers, they lock up and you can't do anything else until they're finished doing whatever.

On trying to spell check this post, words with apostrophes were not found in the dictionary. Maybe I have to be in some kind of text mode, but I can't access the status bar to find out.
