Good ol’ wikipedia, always there to give you a thorough explanation of a particular topic. Here’s a more common language definition of Android — “it’s a kick-ass operating system for mobile devices. It’s based on the Linux kernel and is backed by Google.” Is there anything else you really need to know about it!? The device, by itself, isn’t all that special. What makes this baby sing are the apps found on the app store — Google Play.
