Well, first, Microsoft isn't abusing any monopoly power with the latest version of Word. There is a free ".docx" to ".doc" converter available from Microsoft here:

And the latest Mac and Win versions of Word can both open and save into the old format.
No one is being left behind by the new format, nor are they being forced to upgrade.
Do Office 2007 and 2008 have “one time” preference settings to set the default save format to the older “non-XML”?
Yes. In Word, in the Word menu choose Preferences; click on the Save icon; in the dropdown menu: Save Word Files As, choose Word 97 - 2004 document (.doc).
What file format are most Office 2007 for Windows and Office 2008 for Mac users actually using?
It would be hard to tell without taking a poll. But I am receiving plenty of both.
Are there genuinely desirable features available only with the “x” format to induce users to favor the new format?
I understand that the new format allows quite a bit more stability while working with Word than the old format. It also allows for smaller file sizes and the implementation of new features.
