I was wondering if the Digital One Rate and Single rate plans are that far ahead in coverage to pay the premium.

Does anyone know how the coverage compares accurately in percentage terms? In area? In metro's covered?

Seems to me I read somewhere Cingular is within single digit percentage points in coverage and will exceed Verizon's coverage after the ATT deal is closed.

I was on digital One Rate for ATT the first couple years when I realized I did not travel much outside the network and i would have been better of paying the roaming charges rather then the premium for the "care free" national coverage.
