People who use a RIM Blackberry Device on a very regular basis are sometimes called CrackBerries. For some reason, one finds the Blackberry device so easy, and so powerful, that they would find it hard to live without one. Let’s face it, email, push notifications, and one of the best access to applications, it makes sense that such a phone has an appeal.
One may even say that the Blackberry may have been responsible for the demise of the Personal Digital Assistant (PDA). They are able to do everything your old PDA could do, and make phone calls as well. In a matter of fact, you could use the PDA’s Contact Directory to make calls from.
