I sympathize strongly with the people who lost their job. I don't, however, sympathize with the company that made their decision to go it alone despite overwhelming evidence that there isn't room for another platform. iOS, Android, the Web. That's it. That's all there's going to be for the foreseeable future in mobile. Even Microsoft is failing at this. How much evidence does a company need to see that their strategy…
The BB, Nokia, HTC etc problem is one of cash /runaway. Nokia was almost broke and how many $950M loss quarters can BB take? Not that many. Microsoft can keep bankrolling Windows Phones for a decade waiting for iPhone and Android to make mistakes and no one will even question them.
Look at what they've done for xBox and Bing.
