Android for Education
Android is a great operating system with a lot of great features and apps for education. Most of my students have Android phones, with a few having iPhones. Android phones make up more than 50% of the smartphone market, so it is very widespread. It is rare to find an app for iOS that is not available for Android (and vice versa). Android works great with all of Google's many apps and resources (kind of obvious since Android is made by Google), so if you use a lot of Google's apps, Android is a great option for you.
