I received my phone on Tuesday and have been giving it a workout in the Washington, DC and Baltimore areas. Call quality has been extremely good and I haven't dropped a single call to this point. During my commute home on 66 every evening I have two spots where calls would drop on AT&T. No drops to this point.

Overall the Nexus 6 is a pretty good phone and I've been impressed with the battery life. Couldn't make it through a full day on my Note 3 and the Nexus 6 lasts me all day with back-up. Camera seems to be ok on the back side and a bit lackluster when shooting in dimly lit spots.

I will be testing in SE Virginia on the later part of next week and will provide a quick update. Should be a great opportunity to see how the Sprint portion goes as T-Mobile has no coverage in the area I'm going.
