The only thing that kept a couple of users on Blackberry in my last job was the free international messaging on Blackberry's system. Doing business overseas, people found that to be the one perk that kept them from switching. Now, free messengers are becoming common enough that even those specific users no longer care. One switched to iPhone and I don't know what the other main Blackberry guy is running at this point, as we haven't kept in touch.

Blackberry Enterprise is one of those products that I really just have to scratch my head at. It has always seemed to me that encouraging users to treat as secure something which is easily lost, stolen, or damaged is a fundamentally flawed concept for a business model. Sure, there are users out there who have a genuine need for such a concept, but the problem that really needs to be addressed is user understanding of data security practices, not giving them technology that encourages continuing bad practices in ignorance.
