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. All that means is that they've decided it's not worth investing the money in trying to make them any better than they currently are; 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. A beagle board sounds awesome, for example, but it's targeted as a media/thin client type of device... until I can find a lead on an ARM/OMAP board designed with ethernet ports or at least miniPCI/WIFI expansion options things like ALIX are still the road of choice.
