Great insight, Comcast would love to be able to offer a turn key quadruple play to its customers.
(landlines, cell, home video/mobile video, and home inet/mobile inet) and Comcast unlike Sprint or other carriers already owns programming content.
All in All It would leverage/enhance their core competencies and revenue streams by expanding their potential subscriber market base and reducing subscriber turn over.
Comcast would be a one stop shop imho
