One of the major advantages of Blackberries over other PDA-style phones, particularly if most of your friends are already on the Blackberry Bandwagon, is access to Blackberry’s proprietary Blackberry Messenger software platform. Blackberry Messenger, or BBM, operates through RIM servers, much like email, so it incorporates Blackberry’s famous “push” technology.

Also, users can share media and include a whole range of “smilies” and other icons in their messages. For users that utilize it frequntly, it can be quite addictive. And it can absolutely be incentive to go with Blackberry instead of iPhone.
