I wrote in June of the need for Microsoft to deliver cross-platform support for Mac (and Linux users) to combat efforts from both IBM Lotus as well as Sun's OpenOffice. Today comes news that Microsoft will abandon Entourage for Mac and release a version of Outlook for Mac at some point in the future. Microsoft is also released a business edition of Mac Office with improved Exchange and Sharepoint integration. Still, with these products being developed by a separate BU they are still different from their Windows counterparts. Microsoft needs to set a goal of one application for all platforms.
