Microsoft Office including Word, Excel and power point is available for free on Android and iOS devices. It means that you don’t require a subscription to Office 365 for using Microsoft Office.
In the other hand Microsoft has entered an agreement with Drop Box Company to integrate its cloud storage service into Office on mobiles, tablets and home computers.
Office accounts make for about a third of Microsoft’s annual revenue, according to the New York Times, so letting people access it for free is a big risk. Although Microsoft will continue to charge for access to Office on laptops and desktops and also some special features on mobile apps are only accessible to premium users. iOS version of Office is available from today and the Android version is available as a beta version and will get a full release in 2015.
