Cisco predicts that by 2015, there will be nearly 15 billion network connected devices, up from today’s 5 billion devices. This will be driven by the surge in tablets, mobile phones, connected appliances and other smart machines. They also predict a growth in number of Internet users from today’s 2 billion to 3 billion. That is only an increase of 50%, which means that each one of us will double the amount of connected devices up to an average of 5 devices per person. Personally, I think this estimate is too cautious.
