Apple has really outdone itself with its new application iCal. Apples integration with between iChat, Mail (why not iMail?), Address Book, and iCal is amazing. If you go to email a person in your Address Book who is online in iChat you can just click the iChat link to start a new AIM conversation. Want to tell your friends about a party you’re having? Drag them onto the event from Address Book into iCal and send the invitations – they just double click to add it to their iCal. How cool is that?
