It seems fitting that a morning in the company of Jim Balsillie, the joint chief executive of RIM, the company that makes the BlackBerry, is spent on the move, leaving a meeting and walking at a fast clip through the crowds at Mobile World Congress in Barcelona, waiting with others for transport to leave the show, and finally in a car, snaking through the traffic on the way to another meeting.

BlackBerry customers are now roughly split between consumer and business users. “Our subscriptions are being added faster in consumer than enterprise,” Mr Balsillie says. “The consumer market is very open right now.”
