Just loaded Leopard yesterday, and I finally want to move my life and business out of Entourage and move to the Mail/Address Book/iCal/.mac combo.
I get how to move the Contacts and Calendar events: just use Encourage 2004's built-in sync. Works very well, and happens in just 10 minutes or so.
I'm now wondering about all of the Categories and POP email accounts (I have 9). I have 4200 Contacts. It'd be great to know if there's a way to assign the Entourage categories to the Address Book categories. Otherwise, those 4k contacts will take a long time assigning their correct categories.
Any ideas from switchers would be most appreciated.
