Amazon App Store for Android tablets
Google's official Android Market, Play Store, is a great place to find quality Nexus 7 software, but the true app connoisseur always appreciates new options. Amazon's App Store is one of the best Android Market alternatives, if not the best. It provides a number of unique features and offers, including a new, normally-paid app for free every day, and a cool Test Drive feature for trying out new software. You need to tweak a few settings to download the App Store, but Amazon details the process on its website, and it's worth the hassle.
