$BB BlackBerry's could not turn around overnight and it has been just about 10 years since Chen took over. How long did it take for Apple? Jobs left in 1985 and returned in 1997 that was 12 years and it would be another 10 before the iphone came out. It was not an overnight success but took until 2010. That's 25 years for Apple to right their business. BlackBerry's "iphone" moment is upon us. You can wait if you like or leave just before it launches.
