Zinio for Android Tablets
Google's Play Magazine store is a good place to find digital magazines optimized for your Nexus 7 tablet, but the similar Zinio online magazine service has a larger selection and one very important difference: Zinio lets you read your magazines on a variety of different devices, including PCs, Macs, smartphones and tablets. You can only read Play magazines on Android smartphones and tablets. Zinio's flexibility can be invaluable if you want to read your magazines on non-Android devices.
