> the firmware was hosed in such a way that pretty much all units would fail over the course of a few months

I initially had some good experiences with the android version which then got more and more unreliable until I stopped using it altogether. I was led to believe that this was due to bugs in the android app. Are you now saying that it is actually a firmware bug on the devices?

And if yes, is there any hope to have this fixed once everything is open sourced?
