Thorsten Heins Named RIM's New CEO: Twitter Reacts

On Sunday night, Blackberry-maker Research In Motion announced that co-CEOs Mike Lazaridis and Jim Balsillie would step down from their positions. New CEO Thorsten Heins took the reigns on Monday, after just four years with the company as its COO.

According to Reuters, analysts expressed doubts over the decision and the effects it would have on the struggling company. "I'm not sure this is what people really wanted to see - it might have a little too bold. It seems a bit aggressive," Shaw Wu of Sterne Agee told Reuters. "It remains to be seen whether these moves are going to be effective or not."

"I am not sure that an engineer as new CEO really gets to the central issues faced by RIM," said Michael Urlocker, an analyst at GMP Securities in Toronto, per Reuters.

During a Monday morning conference call, Heins was bullish about the future of RIM. From AllThingsD's liv blog of the call: "'I don't think there is a drastic change needed', we are 'evolving.' 'I don’t feel I was held back in any way to do what we needed to do.'
