Too untried & unsafe. People will see over the next 12 months if their devices will work without major hacking, or are just hold together with duct tape in same way like N900 et al. I really hope it's not Nokia all over again, and major (mainstream) devs can be convinced, not just relying on freetime devs and communities. Otherwise it would be not much more than a portable SSH terminal with a shiny UI that also can (take) calls.
