Well it would seem they developed the board for some unknown embedded market. That is why you see the Zigbee module, the non-standard (at least for "normal" desktop boards) memory, and other embedded features that really just add cost and will never be used by OS4 users.
Would be nice to have a new "normal" desktop board like the AmigaOne's or Pegasos-2.
When I say normal I mean normal ports, expansion slots, and memory slots.
DDR2, PCI-E, PCI...
