Just finished setting up my Exchange 2003 server for Mobile Access and it is SWEET! Imagine being able to sync mail, calendar and contacts - without Active Sync running on desktop somewhere - from anywhere in the world you can get an 802.11 signal. This solution also allows for web based mail to PPC basec devices. It is essentially the most used features of Exchange based Outlook to go.
The only thing left to sort out is getting SSL running on the Active Sync end. SSL based web mail is working great.
