Apple spruces up Siri virtual assistant in iOS 9 - CNET

Apple's voice assistant, Siri, has a new look as well as a host of enhancements. At its Worldwide Developers Conference on Monday, Apple unveiled some key changes to its voice assistant. Siri boasts a new interface so it looks a bit more appealing. But perhaps most notably, Siri will be able to remind you of appointments and other events. That's a key enhancement as it's been one of the most unique features to Microsoft's Cortana voice assistant.
