• iCloud: Store documents in iCloud and keep them automatically up to date across your Mac, iPad, iPhone, iPod touch, and the web. Changes made to a document on one device automatically appear on all your other devices. Requires iWork for iOS 1.6.1 or later installed on iOS device.
• Dictation: Speak words, numbers, or sentences and watch them appear in your presentation, document, or spreadsheet.
• The iWork apps are also enhanced to take advantage of the Retina display on new Mac hardware so presentations, documents, and spreadsheets appear sharper and more vibrant.
