RIM will remain the choice of companies and governments strictly due to BES; no other OS offers such direct central control over the users' devices. Companies (mine in particular) are struggling to cope with Apple and Android devices in the enterprise, and Windows Phone 7 only slighty better.
I wouldn't bet on this forever. There are increasingly good tools to manage at least iOS devices in enterprise environments, and the platform security features of iOS are nearly as good as Blackberry. In the BYOD world (which is growing), you can deal with less management of devices (enforcing some minimum standards), then layering stuff like Good on top of them to secure business applications.
In the BYOD world, very few people will be bringing Blackberries to the party.
Yup, agreed, and RIM seems to be reinforcing that effort with BlackBerry 10. Moreover, they're branching out across platforms with their Mobile Fusion efforts. They know that going forward, BYOD is going to happen, and IT admins will want to manage the access those devices have. It's RIM's hedge against the failure of BB10. If BB10 fails, they can at least pivot into an mobile enterprise services company.
