Can't answer about ATT cause I don't live in your area. I do know that when I was in SF for Oracle OpenWorld I had zero issues with reception. Where I live ATT is pretty darn good...but not as good as Verizon.

I am a Google fan - my family runs on Android phones. My customers do as well. That said I jumped ship when the Lumia 920 arrived and frankly I have no regrets. The Lumia 920 is an outstanding piece of hardware. I am most impressed with the battery life. I have 5 email accounts linked (15 minute poll) and the phone goes easy 18+ hours before needing a charge.

The major drawback moving to WP 8 vs iOS & Android is the much smaller application market. For general purpose stuff the apps are there but for customized apps I think there may be a give. If the WP market will catch up depends on the user base. Lots of people out there with negative views on anything Windows....that is a major hurdle to clear. I find the WP 8 user experience refreshing. YMMV.
