A lot smaller and just half the weight of a full-sized iPad, the iPad mini squeezed the features of the iPad 2 into much more portable package with a 7.9″ screen.
In 2012, The New iPad – as Apple called it – got its first Retina Display with a 2048 x 1535 pixel screen. It also received a quad-core graphics processor as part of its dual-core A5X CPU. It is commonly known as the 3G iPad.
A bit smaller, one-third thinner, and a little lighter than the original iPad, the iPad 2 also moved the iPad line to Apple’s dual-core A5 processor. It was also the first iPad available in white or black.
