Since its creation in June of 2007, the iPhone went without a rival to challenge it for the best smart phone in the market. In October 2008, however, Google answered the bell by introducing the G1. However, it was not until a year later in October of 2009 that Android truly took off with the introduction of the Motorola Droid. In July of 2010 HTC moved from its using Microsoft Windows Mobile and merged with Google Android. Similarly to the iPhone, the Android phones also provide a full touch screen that interacts fluidly with the user and offer accessories such as 5-megapixel camera, Wi-Fi, Bluetooth, and GPS.
