Since RIM's dismal earnings report and its delay of BlackBerry 10, CEO Thorsten Heins has sometimes come off as being in deep denial about the company's future. In an interview with The Globe and Mail, however, he's explained why RIM's next-generation operating system won't launch this year in relatively frank terms. Heins said that though "the core technology of BlackBerry 10 is ready to go... The goal of BlackBerry 10 is to bring some of the best technologies in the world together in a seamless environment. Simply put, I could still see some of the seams," leading him to put it on hold. Heins also says the company has "rejected" the option to switching to Android or Windows Phone 8, contrary to speculation that he's under pressure to partner with Microsoft. Instead, he insists that when BlackBerry 10 will be "the only completely new mobile platform on the market." Despite reassurance that RIM will be sticking to its latest schedule, though, it's difficult to be excited about an operating system that remains so elusive.
