Apple's fourth-generation iPad features the new A6X processor, which is designed by Apple and is said to deliver up to twice the CPU performance, and up to twice the graphics performance, of the A5X chip featured in the previous Retina display iPad.

The new iPad also sports a FaceTime HD camera, improved Wifi performance, and support for additional LTE carriers around the world. It also features the new Lighting connector, which was first introduced with the iPhone 5.

The new iPad will be available on 02 November, retailing from £399.

Apple has also introduced the iPad mini – a lightweight and smaller version of the iPad, featuring a 7.9-inch screen instead of the conventional 9.7-inch screen. The iPad mini is said to be 53 percent lighter and 23 percent thinner than the third-generation iPad, and offers the same 10 hours of battery life.

The iPad mini offers the same resolution as the iPad and iPad2, which means that more than 275,000 apps designed for these models will be compatible with the iPad mini – this includes British Journal of Photography's award-winning iPad app.

The iPad mini features a five-megapixel iSight camera, as well as a front-facing FaceTime HD camera. It uses the dual-core A5 chip and comes in two colours – black or white.

The iPad mini with Wifi connectivity will be available from 02 November, while a cellular version will be released two weeks later. It will retail from £269.
