Amazon Kindle for Android Tablets
Your Nexus 7 is a wonderful e-reader, and the Kindle for Android application brings Amazon.com's collection of more than 750,000 digital books directly to your device. The app lets you purchase books any time you have wireless connectivity and read whenever you have battery life. Many classic books are free, and best-sellers start at just $9.99--less than what you'd pay for a new print version in a bookstore. You can preview books before buying and read them on multiple Kindle devices, thanks to the app's Whispersync technology, which transfers bookmarks and other annotations between devices.
