(CNN) -- The makers of BlackBerry devices, Research in Motion, are gearing up for a fight they can't afford to lose. On Wednesday at a press event in New York, the company will finally unveil its new smartphone operating system, BlackBerry 10, and a pair of new handsets -- one with a physical keyboard and another that's all touchscreen. But are there enough BlackBerry fans left out there to embrace a new kind of smartphone from a company that has fallen woefully behind the competition, both in sales and innovation? Many BlackBerry users in the United States are stuck with the device because it is issued by their employer, which has led to a cumbersome trend of people carrying two devices: a work phone and a personal one.
