The initial noises out of the shake-up at Research in Motion, although it was more far-reaching than had been expected, are not especially encouraging for the investors and analysts who want radical action.

Mike Lazaridis and Jim Balsillie, the joint chairmen and chief executives of the maker of BlackBerries, have relinquished both roles. But they have handed over to an insider who looks determined to stick to the same course.

Thorsten Heins, the new chief executive, told the FT:

“I want to maintain the focus on enterprise, but we need to communicate a bit more with our consumers. We need to do more marketing.”
