Just to clarify something (I noticed this popping up on a lot of sites)... the Geodes aren't EOL-d, AMD simply has declared that they're not doing further architecture development on them. it does NOT mean that they are planning to stop manufacturing them.
I'm still waiting to find an ARM-based system that is available as an OEM board and offers the same sort of expansion/networking options as any of the stuff mentioned previously in this thread.
