The battle is not just about dividing up territories already occupied; it is also about finding new lands to conquer. Both firms are keen to stake claims on the largely uncolonised and still somewhat notional terrain known as the “internet of things”: the myriad processors in industrial machinery, consumer goods and infrastructure, ever more of which will communicate with each other and with distant computers. Cisco, a giant American maker of networking gear, estimates that by 2015 there may be almost 15 billion internet-connected devices, up from 7.5 billion in 2010. Whereas the market for more phones and other personal computing devices is limited by the number of persons the planet has to offer, things, being more numerous than people, provide a lot more long-term room for growth.
