Apple’s iWork productivity suite, Cupertino’s answer to Microsoft Office, takes full advantage of several of Lion’s new features. The "Pages" word processor, Numbers spreadsheet software, and Keynote presentation program all support full-screen mode and autosave, which stores a copy of your work every five minutes or during pauses.

Each component also supports Versions, which automatically creates a new version of a document each time it is accessed and every hour (so you can easily compare changes). Then there's the very useful resume, which restarts a closed app wherever you left off. Autosave is especially welcome, because it will eliminate those panicked 1 a.m. searches for documents that you forgot to save before your laptop’s battery finally gave out.
