Graynomad:
How does the Propeller load it's code?
According to the Parallax community (link below), the module will include external EEPROM via SPI for program storage; that's how its done on Prop-1 modules. No word on size. Provided the integrated module is less than the price of the Due, Parallax may have a winner.

MarkT:
There is an existing Prop I board (Propeller-ASC) compatible with the Arduino
shields, and I have a vague recollection someone's written a software compatibility
layer too (?).
Yes, apparently someone wrote a language called Propellino. At this time, the Prop-1 does not interest me because of lack of ADCs, among other things. For now, I'm staying with the Due, but I will try the Prop-2 when out. A module designed and programmed by the Arduino team featuring the Prop 2 would be even better.
