About two years ago we helped a small firm we know switch its day to day office IT from Windows to Mac. We weren't actually Mac users ourselves at the time (if anything we were a little anti-Mac) but we were 'IT people' and the firm was run by some good friends so we pitched-in and helped. Very much to our surprise we quite liked Mac OS X, it was all-new & no longer just a tool for 'creative professionals'.

Office 2007 introduced a new xml file format for their documents, docx, which seems to have caused some confusion amongst some of our clients. The Docx file format is specific to Office 2007 and doesn't work with other office applications or previous versions of Word. There are a number of ways that docx files can be converted to formats that others understand.

Just dispensed some advice to a client in trouble. It's a little trick that's helped me out a few times before so I thought I'd post it here in the hope others may find it useful.
