Apple to target combining iPhone, iPad and Mac apps by 2021

Apple Inc. wants to make it easier for software coders to create tools, games and other applications for its main devices in one fell swoop - an overhaul designed to encourage app development and, ultimately, boost revenue. The ultimate goal of the multistep initiative, code-named "Marzipan," is by 2021 to help developers build an app once and have it work on the iPhone, iPad and Mac computers, said people familiar with the effort. That should spur the creation of new software, increasing the utility of the company's gadgets. This seems more of a repitition of what we already knew than truly new information.
