iTunes now allows you to sync contact and calendar information with the iPod. iPDA extends the operations that can be performed with the iPod, by synchronizing Word documents, PDA, Apple Pages, RTF or text documents.
Version 4.0 includes “Leopard-specific” syncing with Mail, iCal, and Calendar, including Mail Notes and Tasks. The user interface has also been updated.
Now you can also download RSS entries, download new articles and read them offline, subscribe to the calendars published by iCal and download them directly, as well as make backup copies on the iPod.
The system requirements are Mac OS X 10.3 or later and an iPod. Entourage is also supported.
