There's a well-worn narrative that Apple innovates and Microsoft follows. But as I've often pointed out, the reverse is more often the case. And the s revelation this week that Apple will reportedly bring its iOS mobile apps platform to the Mac is just the latest example.
As you may have read, Apple is reportedly working to bring iOS apps---for iPhone and iPad---to the Mac. This is an area where Microsoft came first: It added a new mobile apps platform, first called Modern and now called Universal Windows Platform (UWP), to Windows 8 in 2012. Google followed next, by bringing the Android mobile apps platform to Chrome OS, its own desktop platform; that work is ongoing but it was announced in mid-2016.
