I feel I should explain myself. I understand iMessage is much more than SMS and I love it so far. What I am saying is that is has been difficult to convince friends to use it. They still require a SMS plan since not everybody has an iPhone. Using iMessage will cut into their limited data, while using their SMS plan will be unlimited. Once more people have iPhones, we can ditch the SMS plan and use the "cheaper" data.
