Google has just updated its app for iPads and iPhones.In Google Drive's first release on the iPad/iPhone, you were only be able to view items that you had in Google Drive/Docs and edit the document's permissions. With the newest version, you can now create and edit documents too!
If you are collaborating with someone on a document, the app will continue to refresh every couple of seconds so that you have a similar experience as you do when collaborating on documents from your computer.
The app also supports richer presentations with animations and speakers notes so it has a great potential to lighten your load. If you haven't started using Google Drive yet and would like some help visit during out office hours or email firstname.lastname@example.org and some one will get back to you.
