Windows 8 was released in October 2012 with a new "Metro" interface optimized for touchscreens. Windows 8.1, released later, added features to make the OS more usable without a touchscreen. Both versions aimed to consolidate Windows functionality across desktops, tablets, phones, and Xbox. iOS 7, released in 2013, redesigned Apple's mobile OS interface and added features like AirDrop for easier sharing. Both OSes focused on seamless experiences across connected devices while taking different approaches, with Windows spanning desktop and mobile and iOS separating the two.
