Honest question to current/former blackberry users: what can BBM do that text messages can't? I think that I heard that you can see when your recipient reads the message, but is there anything else? I often hear blackberry users talking about BBM, but when a text message can reach any cell phone user as opposed to just those on one system, I have personally wondered what is so special about BBM.
I realize that this is the iPhone thread, but as an iPhone user myself, I'm genuinely curious about the benefits of this BBM thingy.
