We're familiar with much of BlackBerry's history, but there are a few unanswered questions: why did Jim Balsillie resign his board position, for example? And why did the Z10 launch ahead of Q10, to disastrous results? Thankfully, The Globe and Mail has addressed some of these mysteries through a detailed exposé. We now know that Balsillie left the board after BlackBerry axed an "SMS 2.0" plan that would have replaced carriers' text services with BlackBerry Messenger. Thorsten Heins wanted the company to remain focused on hardware, according to the newspaper. As for the Z10? Heins reportedly prioritized the all-touch phone over the objections of board members like Mike Lazaridis, who saw the Q10's keyboard as necessary for standing out in a crowded market. There's even more to the story than these two revelations, so you'll want to visit the source link if you're wondering just how BlackBerry ended up in such dire straits.
