This looks like a good read: Free Software for Busy People.

“Free Software for Busy People is a new book from Mohammad Al-Ubaydli, a Bahraini MD who is on a mission to help information-civilians understand why they should use free/open source software.
The book tells the story of six people from six walks of life (government administrator, MD, corporate exec, entrepreneur, Arab teacher, primary school teacher) who adopt free software.
The book simply and clearly states the case for adopting free software and provides equally clear and simple explanations of how to switch and what to expect when you get there.
You can buy a printed and bound copy of the book, download a PDF, or read it as a hyperlinked html file.“
