  Quite true, but the long-term fish-hooks in Soft-CPUs are the silicon 
  supply, and the software tools themselves.
  There really needs to be a certain 'critical mass' - and the C51 
easily meets that.

For CPU + FPGA development, you really want to
have coverification, and AFAIK there are two ways to get that;
Send a $125,000 check to Mentor, or get the $100 STK594...
