The suite is clearly intended to take on Microsoft SharePoint and Google Docs, but approaches online document management somewhat differently. Rather than editing and organizing documents only through a web interface, Apple has integrated the online aspect into the familiar native iLife apps as well.

Interesting new trend times. Leveraging cloud-based syncing services for collaboration. It all sounds so familiar. Like a sort of Notes back-to-the-future world where data replication was the goodness to combat network bottlenecks and analog modems. Now it's used to keep all our devices current (and us informed) as we move through the different modalities of the day. Great for info junkies.
