Windows Contacts in Vista

Vista adds a new store for Contacts to the list of such from Microsoft--Outlook, Exchange, BCM, SBA, Hotmail, and so on. Vista's Windows Contacts promises to provide an interface for synchronizing Contacts with other stores. Unfortunately, it's still quite primitive; i.e. COM/C++ with QueryInterface, HRESULTS, and all that 90s crud. I hope they add managed APIs soon. Meanwhile we'll keep waiting for WinFS.
