The Java Desktop System (TM), from Sun Microsystems, is a modern system for all kinds of users, novice through expert. As an unusually robust, well-integrated desktop system, it may become the first to fulfill the promise of mass adoption for open source. JDS brings Linux and other open source software up to a level of usability that makes them suitable for the enormous base of Personal Computer users including office workers, students, mobile and home users. It behaves pretty much the way a Windows or Mac user would expect, but with many more powerful features. JDS has seen widespread adoption in the United States, Britain, China, and elsewhere. This book is the ideal guide to JDS: it is clear and direct, but loaded with insights from authors who have spent time working with, supporting, and enhancing the system. Tom Adelstein is an award winning polymath system designer; Sam Hiser is a respected business consultant with an itch that led him to become the marketing project lead for OpenOffice.org. Both are advocates for open source and founders of the Open Government Interoperability Project, members of the Open Source Software Institute and contributors to the JDShelp.org project.
