Canadian Blackberry manufacturer RIM had a torrid 2011, in which it generated a lot of negative publicity by underperforming financially, experiencing a high profile outage, facing calls from shareholders to sell up and seeing its co-CEOs and founders step down. Its message to stakeholders during this difficult time has been a call for patience, with claims that the next software platform to be released will be a real game-changer. So the unveiling of the BlackBerry 10 platform this week was met with great expectation.
