Has anyone used it yet? Does it work well?

I've used it, but must say I prefer Contacts synched by Outlook because when you click on Address book you could start typyng a name and very quickly retrieve it. In MaxMobile however when you click Address Book it takes a while to build list and then you still have to click search options ie Last Name or First name etc. It takes much longer to get to the contact. Just some initial thoughts.

The advantage you have with Max Mobile over standard contact sync is the history attached to it. Max Mobile is an actual application rather than just a list of contacts.
