The Globe and Mail this week published an extensive investigative report on the dramatic rise and fall of BlackBerry, detailing some of the high-level disputes that ultimately plagued the smartphone maker. Underpinning the drama was a philosophical debate on the company's future, and arguments over how to respond to the launch of the iPhone. Tensions came to a head in a board meeting late last year, when CEO Thorsten Heins discussed the Z10 with BlackBerry executives. Co-founder and former co-CEO Mike Laziridis warned Heins against coming out with a full touchscreen phone, urging the board to instead focus on its trademark keypad devices and strong enterprise base, but BlackBerry ultimately sided with Heins. The Z10 was a flop and months later, BlackBerry's future is more uncertain than ever.
