[sdiy] Propeller CPU

[Adam Schabtach]

FWIW, awhile back I looked at the literature on the Propeller (including
reading the programming reference) and arrived at the same conclusions as
Antti. At first glance it's interesting, but it's not clear that it offers
performance advantages over the ATmega family once you start using up its
cores ("cogs", rather) to do things that are handled by the hardware
peripherals in other MCUs. 

Just my $0.02 worth, of course. If it really intrigues you, give it a try!
The proto boards aren't terribly expensive so you can play with one without
putting out much money.
