Price is the chief arbitrator of a sale in paging. Interconnect companies sell and install phone systems and perhaps computer networks. They aren't geared to move in these new circles with their image as interconnects. More power to them. The good ones will prosper.
Cellular agents are almost always something else first, with cellular phones as an adjunct.
That makes them convenient, but not diversified communications companies. Phone companies are just that- phone companies, institutions. They simply don't exist in any known category that the topical human being can locate. I don't think a make-over will do. We need to come out of the primeval dark and land our sleek new ship smack into the middle of the grey-tone world of yesterday's technology.
