My data is continually corrupted. Fields are imported from Address book into different areas, data duplication, etc.

Also, if you add new address info directly into Outlook, it does not push that data back to Address book such that it is integrated with other computers one might have. I have a 27" iMac at work and a 17" MBP at home, and I can't keep data synced well. Yes, entering it once in Address book should cause it to be added to both machines, but somehow none of that works right. I suppose that's one reason for the proliferation of apps on the App store that are designed to find and eliminate duplicate addresses.
