Rollout no longer gradual
The iWork for iCloud beta is now accessible by all iCloud users. Web versions of the iWork apps -- Pages, Numbers, and Keynote -- were initially restricted to developers, but then gradually began reaching the general public through the beta iCloud site. Today, though, the iWork apps have been independently pushed to iCloud.com.
Although they're simplified versions of their native Mac and iOS counterparts, the apps let people view and edit iWork documents from any computer with a compatible web browser. Files are automatically synced between devices, making it possible to do quick edits when away from a Mac or iPad.
