Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2012–2017 [Visual Networking Index (VNI)] - Cisco Systems:
"... By the end of 2013, the number of mobile-connected devices will exceed the number of people on earth, and by 2017 there will be nearly 1.4 mobile devices per capita. There will be over 10 billion mobile-connected devices in 2017, including machine-to-machine (M2M) modules-exceeding the world's population at that time (7.6 billion). ..."This is pretty much in line with some statistics I heard at a recent VMware event in St.Louis. When asked how many people in the auditorium had a mobile device with them, nearly all raised their hand. When asked how many had 2 or more devices with them, a clear majority raised their hand.
I would have to point out that the several hundred people in the auditorium did not represent a random sampling of the public, but with the ubiquity of smart phones it isn't to far a stretch to believe that 2013is the year when the number of mobile devices (laptops, smartphones. tablets, etc) will exceed the population on Earth.
