Where does time go?
One day, I’m reading that mobile phones used by commercial vehicles would be getting a new ability to pass signals from site-to-site in a cellular network – and all of a sudden, 40 years has gone by and we all have them. Forget the bags and the bricks. Forget the shoe phone. But rumor has it that Apple and Samsung (names we didn’t even know 40 years ago) and others may soon have wrist phones – not unlike Dick Tracy’s wrist communicator of our childhood. To commemorate the 4oth anniversary of the cell phone (sort of), Business week takes us down memory lane.
