Million dollar BBusiness idea.
Here you go RIM, no charge from me:
1. Sell your hardware biz to whoever will buy it, you might have some worthwhile patents for Google/Apple to snap up, and you've always made the best 'phone qwerty keyboards.
2. Lease your BBM software to all platforms. They'll snap it up. If BBM was ubiquitous, available through web browsers, Android, fruit based electronics, etc., yet retaining similar levels of security / centralised enterprise control, it would be a game changer.
