It doesn't come as a surprise that Microsoft Office on Android and iOS has finally crossed the 100 million download mark. And it isn't just because the productivity suite is now free on Android and iOS. It shows how much Office is in demand across platforms. The goal is obviously to get more people to pay or subscribe to Office 365 service. There seems to be a boost in that area as well as the company says there are now 12.4 million consumers paying for Office 365.
