The free Amazon Kindle app has finally arrived on the Android Marketplace today. The app will give you access to the Kindle store with over 620,000 e-books to purchase and download to your phone, or preview it for free before doing so. Plus, you can sync books and bookmarks across multiple devices with access to the Kindle app such as Android, iPhone, iPad, BlackBerry, and of course the Kindle itself, which by the way recently got a price drop. E-book + Android lovers can live happily ever after.
