At the Build Developer Conference on Wednesday, Microsoft shocked us all by announcing that Android and iOS app developers would be able to port their apps to Windows 10.

Anyone who has ever used a Windows Phone will tell you how lacking the devices are when it comes to apps, but by giving developers a simplified process with which to port the apps to Windows 10, Microsoft might finally be competitive once again in the mobile arena.

Finding out how much work will be necessary to get an app up and running on Windows 10 is as easy as dragging and dropping it into the analysis tool on the Windows developer portal. Microsoft will even give developers guidance on the recommended steps to take to get the app ported successfully.

If it’s really as easy as Microsoft makes it look, Windows 10 and Project Astoria are going to revolutionize Microsoft’s mobile ecosystem.
