Yeah, finding the right dead zones would be pretty hard. Especially if you are somewhere with relatively good signal. Would be a very interested in the results.

Disappointed with that 2 seconds though. I was really hoping for smoother. Though I guess that is why they are still invite only. They are still working on the technology. I was leaning towards getting Fi when the new Nexus comes out, but this makes me think it might not be ready yet.

Thanks for all the info.
