Pages, Numbers and Keynote are now universal titles, continuing to offer an expanded, more complex interface on iPads. Pricing also remains a consistent for each title. Each app has further gained a new document manager, which should make it easier to sort through files and arrange them into folders. Pages and Numbers have been enhanced with a feature called "Smart Zoom," used to view and edit data. Among some app-specific updates are font size and style controls on Pages' ruler, and the option of using Keynote Remote to operate Keynote from another iPhone or iPod. The decision to release iWork for the iPhone this week may hint at the nature of Apple's WWDC keynote on June 6th. It suggests that the company wants to leave room for other topics during the keynote, of which there could be many. Dominating the event will be demonstrations of iOS 5, and iCloud, Apple's mysterious cloud service. (Also Mac OS X, Lion.)
