As of September 19, 2013, Google has freed QuickOffice for everyone. The result? Anybody with a Google Apps account can edit MS Office documents — Word, Excel, and Powerpoint — stored in Google Drive using any Android or iOS device.
While Microsoft is still attempting to lock users into Windows platforms in order to use MS Office, Google Apps and Google Drive users can now freely view and edit documents across platforms.
Combined with CumuluSuite Office, you can integrate MS Office on your existing Windows or Mac devices with the ability to view and edit them from smart phones and tablets.
