I finally found the time to publish the Eclipse 4 RCP book also as Kindle version.
Amazon USA: Eclipse 4 Rich Client Platform
Amazon Germany: Eclipse 4 Rich Client Platform
The other Amazon countries should also be available soon, please see Eclipse RCP book page for updated links.
This book is relative large, depending on your Kindle version and text size settings. During upload Amazon reported that the book has between 8000 and 10000 Kindle pages. The paper version has approx. 700 pages.
