have you looked at the functions of the built-in Address Book? It may not suit but is worth a look.
Now make an OS X version of their Contact software which you can see Here

Morning,
Looking for a contact management software recommendation. Currently using Personal Organizer 4.5 from Chronos to manage about 4000 contacts, send email, record notes, generate mailing labels, etc. Their latest version slows machine way down (OSX 10.4.11, 2GB RAM).
Also curious if 4.5 will work with Leopard. Not willing to risk a lot here.
Thanks!
