Free stuff is good, and if you're an Android developer looking to get into the Intel dev scene, then there's a free book on Amazon that should be just what you need. It's called "Android Application Development for the Intel Platform" (man I really love catchy book titles), and it's normally $40. The paperback version is still going for $35, but if you can handle reading on your device, the Kindle Edition costs approximately zero monies right now.
