Each of the major operating systems on the market today is generally incredibly well designed and fit for its purpose. It is the purpose that needs changing. The next operating system I will use will allow me to log in from any terminal anywhere in the world and receive the same experience. The OS will be a simple abstraction layer over my individual data, preferences and even personal UX. It won't matter if I'm looking at a phone or a tablet or a television or my refrigerator, the interface will be tailored to my context and all the same data will be accessible. Many would argue thnt the web is this OS, and they would be right in many respects. But the main desktop and mobile and refrigerator experiences are still vastly separated; the next OS will remove this separation, as it no longer provides us with any advantage in the great majority of cases. OS wise, this would bring many challenges. How do you securely sync data, and more importantly, code? Where does a user and their data live when not logged in? How is all the data transfer handled in an efficient way? What lives on each device versus on a server somewhere? How can a user continue to own their data and devices, rather than having them appear amorphous and distant? How do you keep a universal and omnipresent feel without sacrificing the power of using native hardware and capabilities? Certain cloud services have come far in this area, but none have been ambitious enough to tackle the whole experience. Do that right, and the world will be yours.
