I don't have recent experience with Forth, but traditionally, Forth didn't require such a "beefy" machine as a C programming environment.

For instance here's a fairly complete Forth environment in around 10 KBytes running on an 8-bit home computer. There was no C compiler at all for that machine, and if there would be, working with it would be a lot more hassle than a Forth REPL.

What's the appeal today, I don't know. But I'm in the "curly braces" camp. If I'd be a Lisp guy, Forth would probably be more appealing to me.
