I don't know whether to be pleased that Microsoft appears to have renewed interest in developing the Mac versions of their software or dismayed that (after all these years) they admit to needing help just understanding what Mac users want. In any case, Microsoft has a web page where they are conducting a survey of Mac users. They state:
"Microsoft is committed to making great products for the Macintosh that address the unique needs of the Macintosh user. Your feedback on this survey will help us better understand the characteristics Mac users look for in the software they purchase and use. We will use this information to prioritize our work on future versions of Microsoft Office for Macintosh."
