You don't need to spend extra money on Microsoft Office software; sure it might be what you have used in the past, but iWork is just as good, and a lot cheaper. iWork can help you easily create spreadsheets, calendars, graphs, newsletters, presentations, and much, much more. This guide will show you exactly how. It covers Pages, Keynote and Numbers; it also covers one of iWorks newer features: iWork.com--a powerful tool that lets you share what you have created online.
The guide is based iWork '09.
