If blackberry wishes to remain a force in the smartphone/tablet market it is going to have to address messaging between playbook to playbook, playbook to other devices as well as blackberry smartphones. This would be a huge step for blackberry to capture a larger share of the market. Even iPhones will talk to iPads iPods and vice versa, my playbook however is stand alone as I cannot message other play books. The new bbs for android and iOS is unavailable for playbook and doesn't talks to iPads. While it is great to have proprietary systems, messaging between many devices would be a boon to all, but especially blackberry.
I think he was referring to when BlackBerry had promised OS 10 on the PlayBook and used that as a marketing technique to sell PlayBooks, and then they turned around and told everyone that it wasn't going to get OS10. That was a huge blow to BlackBerry's trust.
Have been a playbook owner since day one, had doubts that BB10 would come to playbook at time of announcement, not having BBM on it is not a problem, I use Z30 as playbook replacement it does everything in one package probably BlackBerry's finest, they can get it right, use enjoy and move on.
Trust is the issue. BB made promises and reneged, might explain some of the financial issues the company is in today. I liked the Playbook which had many superior features to the iPad, but I was also expecting BB to support it more vigorously. Even Apple gives credit for turned in obsolete iPhones and iPads. Technology does change, but in regard to Playbook, BB just abandoned all those customers.
