I have been waiting for this for so long! I’ve tried almost every available contact management system trying to find one that does it all. (de-dupe, sync, update) Plaxo, LinkedIn, Gist, Outlook, Excel, etc. I’m really hoping that this new feature really helps the cause. It would be so nice to finally clean up the mess that I call an address book.
UPDATE – I ran it for the first time, and it literally merged a third (1/3) of my address book! It did a decent job, now I have to fine tune it all, but it actually worked! It’s non-destructive, meaning you won’t lose anything, so you really have nothing to lose! Good Luck, and let me know how it turns out for you.
