Remember a few months ago Microsoft introduced its Office suite on Android? At that point in time while it was announced for the whole Android platform, it was not immediately available for use for users in the East African market who could not take advantage of their existing Office 365 subscriptions to access Microsoft Office apps on their mobile devices. However at the moment all that is possible so if you have an Office 365 subscription, an Android smartphone running at least Android 4.0 Ice Cream Sandwich then go ahead and sample it.
Microsoft Office mobile is already available on iOS devices (iPhones) and is said to be coming to the iPad when Microsoft is done creating a touch optimized version of Office.
