Microsoft CEO Satya Nadella, speaking before the launch of new Surface devices in New York, told glossy tech rag Wired the operating system is "no longer the most important layer for us".

"What is most important for us," he continued, "is the app model and the experience. How people are going to write apps for Duo and Neo will have a lot more to do with each other than just writing a Windows app or an Android app, because it's going to be about the Microsoft graph."
