While I've met many of the guys who work at OpenMoko and think they're great engineers, OpenMoko just isn't any sort of serious mobile platform. They can't even claim the kind of industry support SavaJe had before they went tits up.

They're also making a touch screen handset/platform which makes them automatically a niche player everywhere except China. If one of the first tier handset manufacturers expressed some interest in the platform, it might be worth considering, but in advance of that extremely unlikely event it's just an amusing novelty.
