When I wrote the question I was simply thinking from an ease-of-use point of view, more than a practical standpoint. I have mostly worked with processors with abundant flash and ram.

Clearly theres demand for them, but I don't really see why. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
