I posted this on another thread, but it seem more appropriate for this one...
"...if Apple is working on an office type app, they could be developing each peice seperatly, ie: word processor, spread sheet, Keynote, Mail, iCal, and Address Book, then bundle them together once they're good enough to compete with M$ Office.
I would like to see tighter integration of Mail, iCal and Address Book, something like M$ Entourage. Not neccessarily one big app, but be able to link contacts with appointments and e-mail. I like that feature in Entourage. I can look up a contact and find when and if I had an appointment with that person, or go right to the e-mail that I either sent to or received from that person. I can also color coordinate contacts, appointments and e-mail, depending on category. An example are my customers; I have a category called "Customers" which is colored green. Any appointment or e-mail that I have with a customer is colored green also.
