This is not really new technology. In 1985 IBM gave us hand held Motorola RF connected terminals. It was very similar to the Blackberry but it was big enough so the keyboard and display were actually usable.
We were mainframe connected, RF mobile so we could basically do anything you could do from your desktop <network connected> machine, walking down the street. We could pull/update calls, order parts, check on parts, report hours and parts use, chech inventory status on equipment, instant message between users and send Email ... TWENTY YEARS AGO !
