It seems like the whispers of Android apps running on Windows 10 are getting stronger. Though that doesn't necessarily make them true, it does make the upcoming BUILD developer conference even more interesting if Microsoft does decide to drop the bombshell there. It's not like it's never been done before. BlackBerry 10 OS and Sailfish OS do employ such a compatibility to some extent. It's just that it's never been done officially on Windows before. But while the idea seems almost enticing, it could very well be suicide for Microsoft's primary platform.
