Microsoft began offering a preview of its Office apps for Android tablets this week. Beta versions of Word, Excel and PowerPoint apps are now available (no invitation required) via the Google Play store. According to Microsoft’s 365 Team, users need ARM-based Android tablets with KitKat or Lollipop (and 7- to 10-inch screens) to install and run the preview apps. “As expected, the apps are freemium versions, meaning you can create documents and perform basic editing. But you’ll need that Office 365 subscription to do more,” reports CNET. “The finished version of Office for Android tablets will be available in the first half of 2015.”
