I voted Server Sync to Exchange 2003. I got hosting specifcally to use this feature as I hardly ever synced my PPC to my home machine, and found myself more often sending/recieving home emails than I did when I was using the desktop sync for my work email.
I have an IMAP account to sync my work email
I just love the flexibility of Exchange 2003, I have ActiveSync for my PocketPC, the Outlook Mobile Access for my PocketPC and WAP phone and Web Access for desktop use!
Edit - A couple of people have asked me what hosting company I am using, they are called eoutlook and can be found at
www.eoutlook.com Hope that helps
