In general, hardware products that appeal only to hackers (OpenMoko, Neuros, OGP, etc.) fail while hackable mass-market hardware (G1, WRT54G) succeeds. You can't ship a "rough" product and expect the community to polish it, since polish is what the community is worst at and peer production is so slow that your product is obsolete before the community can finish the firmware. Also, hacker hardware is expensive because it lacks economy of scale.
