The future will be full of a wide array of personal electronic devices with various purposes, with the distribution likely weighted towards multipurpose devices rather than single-purpose. But the future of devices will not be dominated by three big companies. Twenty years ago, almost no one knew how to build consumer software. Ten years ago, almost no one knew how to build consumer hardware. But DIY is no joke, nor is open innovation. Over the next ten years, I expect we will witness the emergence of multipurpose devices and tools built on a much more open model than is even imaginable in our world of picking one of three networks, one of several devices, one of three OSes, and one of a few development platforms. The open future is on its way!
