"Tech companies are like sharks. Either they move forward or they die" - Steve Ballmer
BlackBerry, for too long, did move forward with innovation. It's sad, but this is the end. Revenues are dropping, and even if they sell 5 million Z3s, the profit margin on low ends would not be enough to save them.
Indeed. The only reason Windows Phone has been able to last so long is because Microsoft has enough revenue from other areas of the company to continue taking losses on it. It's beginning to turn around, and Windows Phone is starting to gain momentum, so it has a chance of survival.
But BlackBerry made ALL of their money from their phone division, and they waited too long before they considered thing like BBM on other platforms, or selling themselves as an enterprise services company.
So now they're going broke, with no other means of revenue. Sorry for anyone who likes BlackBerry, but they're done. They probably could've made it if they had put BBM on iOS and Android sooner, or perhaps pulled an IBM and become and enterprise solutions company. But they remained stubborn trying to insist they're the best option for business, and then tried to force its way into the consumer market.
With enough time, this might have worked, but Blackberry didn't have deep enough pockets to try this method, and the end result is what we see now: their inevitable bankruptcy.
