What is Android ?

Android is a Linux-based operating system designed primarily for touchscreen mobile devices; such as smartphones and tablet computers.  The OS was developed by Android, Inc., which Google backed financially and later bought in 2005. The first Android-powered phone was sold in October 2008.

It is now being used in other products as well such as televisions, set-top boxes, etc., as devices are becoming more smart. Being an open source software, it can be customized by manufacturers to make it fit for their devices.

Why Android?

This can be an important factor for users considering that Android devices can integrate seamlessly with Google's array of services. While people are increasingly using their mobile devices to go online and use Google's services, Apple and iOS do not seem to keep up. Although iOS users can also use Google's services, a deep level of integration simply isn't there.
