If you are a regular user of Google Docs you will be pleased to know that Google has now revealed and demonstrated at its Google I/O conference. That Google Docs is now available to use offline.
At Google I/O Clay Bevor, director of product management for Google Apps, demonstrated that Google Docs will now work for offline editing, by opening Google Doc via Google Drive on stage in front of Google I/O attendees.
Once a document has been opened offline all amendments are then saved locally via a local cache on the system, once an online connection has been re-established , the alterations are then synched back to Google Docs.
Google Docs is the first service to be made available offline, but Google is currently working on making their Spreadsheets and Presentations offer the same offline functionality.
