In the opening speech of the MIT Mobile Summit on 10th June 2013 this slide was shown to illustrate and emphasize the current magnitude of the smartphone revolution. It is a nice analogy but the even more impressive figure would have come from Samsung. See picture caption below. It is understandable that these two narrow figures are more appealing in this story context; although this global comparison is kind of outdated as the number of sold smartphones per day has passed the number of births per day long ago and at much higher scale than suggested by this slide…

Actually, Samsung currently sells about 7ooK smartphones every day 🙂 (Source: Reuters)
