While I've free lanced in office suport on and off across the years it's not been my main focus.

I have observed that office workers tend to get on and work with what tools they have, be that old school unix-like point of sale sytems, Wang wordprocessors, god-awful microsoft access hacks, TCL-forms on Sun workstations, cross platform ARC-GIS / ERMapper photogrammetry pipelines, etc.

Drivers, PDF conversion, et al seem to be the bug bears of all platforms I've encountered.

To advance your argument it's really the Excel Macros that serve you best - those things that have developed in-house and are peculiar to a singular anchor software suite.

Offices with no legacy ties binding them to one OS are more agile wrt change, several European countries (Germany at least, there are others) have many offices that are already long time Red Hat (and other) users.
