It has been developed in-house, at Rio HQ in Portland.

It doesn't run "empeg" software because a) we're not in the portables group and b) we haven't done any work to make Linux and our codebase battery efficient.

I haven't seen the software in a while, but it seemed to have some cute features. The battery life is supposed to be quite impressive - I don't know what the official figure is though.
