Kingsoft's newly updated office suite of apps for iPad includes some key features not found in Microsoft's apps.
Among the new features in Kingsoft Office 3.2 are support for viewing, creating, and editing spreadsheets. (The previous version offered only word processing and presentation modules.)
But a key differentiator from Microsoft's Office apps for iPad (Excel, PowerPoint and Word) is that Kingsoft Office supports saving to multiple cloud services: Box, Dropbox, Google Drive, OneDrive, and WebDAV. (Microsoft's apps work only with OneDrive).
