With Microsoft's push to prioritize cross-platform services as well as be a mobile-first company, it's become very important to provide programs on iOS and Android, instead of trying to convince users to adopt software on Windows and Windows Phone.

As part of this strategy the company has delivered Office apps (Word, Excel and PowerPoint) for iOS and an Office Mobile suite for Android phones. Now the company has released a touch-optimized preview of Word, Excel and PowerPoint for Android tablets.
