The iPad is a tablet computer, similar to the iPhone and iPod Touch but with a much larger display - while a typical iPhone has a screen about 4 to 5 inches in size, iPads have screens from 8 to 12 inches big. The first iPad was introduced in 2010 and along with the iPhone, new and better models are made and sold every year. A new iPad will ship with the latest iPad OS software if it is supported.
