If BlackBerry has a realistic chance at doing anything it's taking back the Canadian marketshare it has been losing to Apple ( AAPL) and Google ( GOOG). BlackBerry can win back Canada and solidify itself as the number three mobile platform in the U.S. behind iOS and Android. Opportunity exists, particularly in Canada. BlackBerry must reclaim that turf. If it does the comScore numbers and the trend tell us it will reap rewards. Also, from an organizational standpoint, it will help it regain the confidence it lost in the pre-Z10/QNX days as it imploded under what became an inept management team.
