Snow Leopard Blues – Users of Exchange 2003 should avoid this update

Apple, in its infinite wisdom, chose to implement Exchange 2007 support in Snow Leopard even though the iPhone supports both Exchange 2003 and 2007. So, my desktop system can not access the calendar even though my iPhone has no problem accessing my calendar. I find it hard to believe that they did this when Exchange 2003 still has more installations than does Exchange 2007.
