DO THE FREE MOBILE VERSIONS OF OFFICE COME WITH ANY CAVEATS?
The mobile versions of the Office suite are designed from the groundup for touch and small-screen devices. Using a free Microsoft account, you can view and edit documents, as long as your device has a screen no larger than 10.1 inches. Anything larger (e.g., the new 12.9-inch iPad Pro) requires an Office 365 subscription before you can do any edits. Also, on iOS, you need Office 365 to access and save documents in OneDrive for Business or SharePoint.
