One of the hassles with Office 2008 Mac and Office 2007 Windows is the new document format which ends in the letter X: DOCX, XLSX, PPTX. These new formats cannot be opened in older (and perfectly usable) versions of Office without installing a special (and free) plug-in from Microsoft.

A question recently came past me about Office 2008 for Mac and using old file formats as the default. Fortunately, the folks at MacLife confirmed you can use DOC, XLS, and PPT as the default format.
