Outlook and iPhone

One of my bigger concern before buying the iPhone is that my address book has been carefully maintained in Outlook (Yeah, I know I should have gone Open Source but I need it in order to sync to my WinMo PDA) And from the Google result I have mistaken that I need MobileMe to sync Outlook with iPhone. That's a misunderstanding: iTunes took care of it out-of-the-box. It found my Outlook and asked me what I want to sync (Address book, Calendar...) As simple as that!
