I've (still :-)) got some M4's sat in the corner waiting for me to
look at them. Currently playing with the PIC32MX range.

I still think however programmers should know at least one assembly
language so they have a feeling for how things work underneath and
so they can drop to assembly language on the few occasions when it's
still required.
