There was a time when RIM owned the smartphone space with its revolutionary push email-equipped BlackBerrys. And there are still plenty of folks who can't live without a good physical keyboard and BBM. But, despite the company's $4.9 billion in revenue and $695 million in profits from Q1 2011, RIM's stock has tumbled to its lowest price in five years. What's changed since those heady days when it seemed like there was a Pearl in every pocket? As many of you know, Androids and iPhones have carved out a big chunk of the smartphone market, largely at RIM's expense. Sure, Blackberry 7 OS is coming and the PlayBook is rolling out to help the company gain ground on Android and iOS, but only time will tell if these latest efforts from Waterloo can stem the rising tide of iPhones and little green bots.
