I was waiting for a Firefox OS phone with great hardware, but that didn't seem to materialize (AFAIK). Making both high end and low end phones together, perhaps in different volumes, could have helped. Focusing only on the extreme low end with poor hardware was probably a mistake.
While I'm unhappy that Mozilla is not going to focus on Firefox OS smartphones, I do consider this as an experiment that organizations like Mozilla ought to do. I'm sure there were a lot of things accomplished (like some mentioned in the comments for phone APIs) and a lot of things learned. These will in turn help other initiatives.
Now, please put Thunderbird back on the development track with the same priority as Firefox. :) And while you're at it, we want Persona too! :)
