Forth is not well suited for the Arduino. The Arduino uses an AVR8 processor, which does not allow the program to modify the program-memory during run-time. This means that Forth can't run on the AVR8 unless it is a threaded system with the threaded-code in RAM, but there isn't enough RAM for that. As a practical matter, the only way to use Forth on an AVR8 is to cross-compile --- so there is no advantage over C.

This is largely why I'm interested in the PIC24. The PIC24 does allow a program to modify program-memory during run-time (doing so is somewhat clunky as program-memory is 24-bits wide and your registers are 16-bits, but it can be done), so a Forth compiler can reside on the chip and provide an interactive development environment such as you are describing. The MSP-430 is another good choice, as is the AVR32. But the AVR8 is an old-school processor that really has to be cross-compiled to. 

All in all, the AVR8 is obsolete --- there are a lot better choices available --- other than the Arduino, it is not really used much anymore, although it was pretty powerful for its day.
