Well, let's start with the obvious: BlackBerry is so far behind smartphone OS market leaders Google ( GOOGL 1.54% ) and Apple ( AAPL 1.88% ) that its market share barely even registers. At this point, the former Research in Motion has slowed to a crawl, and is losing ground to Microsoft 's ( MSFT -0.10% ) Windows Phone OS -- but beating Microsoft only lands BlackBerry back in a distant third place. BlackBerry was once the king of "smartphones" before most people used the word to describe the category. Since Apple (and then Google) arose with a new touchscreen mini-computer standard of design, BlackBerry's been struggling to catch up.
