Google Currents for the Nexus 7
Google's Currents app for Android offers a variety of free online reading material in one mobile-friendly location. Currents is basically a souped-up RSS reader with a polished interface that lets you add and find articles quickly and easily. And the service offers high-quality content from a number of reputable sources, including yours truly. The popular and similar Flipboard app is also available for the Nexus 7, but I prefer Currents' streamlined interface and automatic offline-reading functionality.
