The company is reportedly hard at work integrating the best features of its mobile operating system iOS into its desktop OSX operating system. Many believe this will bring the Siri voice-operated virtual assistant to computers as well as tablets and smartphones, but the integration could also include touchscreen commands to complement the smart swipe and gesture-based track pad controls already built into Apple's computer range.
