Just an update of Google Apps vs Microsoft Office on OneDrive –
There are a few nuisances with Google Apps, such as it not recognizing the iOS keyboard Control-Shift shortcut to switch between languages, and no laser pointer in the iOS version of Slides. But when it comes to syncing, Google Apps (Docs and Slides) and Google Drive is a whole different world from Microsoft Office (Word and PowerPoint) and OneDrive.
In Office, with documents syncing through OneDrive, you don’t see the synced changes on either the Mac or the iPad side until you “save” the document. Then syncs are brought in from the iPad and syncs are sent to the iPad (after a bit of time). In other words, there is no real-time collaborative editing of documents. That surprises me. I did a Microsoft Support chat just before, and that was the Microsoft tech person’s opinion as well.
On the other hand, with Google Apps on Google Drive, if you have a file (Docs, Slides) open on the iPad and the Mac at the same time it’s a real-time change that occurs. You can even select text on one device and instantly see it selected on the other device. Very cool! All changes are mirrored instantly on both devices.
Google Apps is a clear winner here on that point. That plus the fact that you can edit for free on all devices (which you can’t do with Office) makes Google Apps the obvious choice to use for class presentations, and for students to learn these basic apps.
