While I agree on the C compiler front (the fact that there are very few free C compiler choices for the PIC is it's most major limitation in my mind), I disagree on the stack point. A stack is by no means necessary in a microcontroller, and in fact can influence odd design choices (of course no accessible stack can also result in odd design choices). I've personally never liked the idea of a stack, it just never settled in my psyche very well.
