Yes, that is a very cool thing about Forth, but I still think there are many aspects of software more easily debugged on a machine with a full set of debugging tools.  It's nice to get segfaults on bad memory accesses instead of silent data corruption, for example.

A live programming environment on the target platform would be great for exploratory programming and determining exactly how the hardware actually behaves, though. Sometimes the data sheets and reference manuals aren't as clear as one would prefer...

Aside from Forth, which has fallen pretty far out of common use these days (as far as I have seen, anyway) there's a cool embedded version of Lua that can run on pretty low-powered hardware. It's not quite as powerful of a language as Forth, but probably easier to pick up and very easy to integrate with C.
