Apple has released the third generation of HD screen iPads - the New iPad - with improvements both inside and out.

Apple officially released the third-generation iPad. The new iPad features a "Retina" HD screen with 2048x1536 pixels, which has four times as many pixels as the iPad 2, and its color saturation is also increased by 44%.

To drive the 3.1 million pixels, which is four times that of the iPad 2, the new iPad is equipped with the new A5X, which has a quad-core GPU, and still maintains a battery life of 10 hours.

In addition, the new iPad also boasts a 5-megapixel back-illuminated CMOS sensor, a 5-piece f/2.4 lens, and a hybrid infrared filter, and supports 1080p full HD video.

However, the new iPad still does not have a built-in SD card slot, and must use an additionally purchased kit to transfer photos using an SD card. The new iPad comes in three capacities: 16GB, 32GB, and 64GB, priced at $499, $599, and $699 respectively (Wi-Fi version), and the Wi-Fi+4G version requires an additional $130.
