Apple's second-generation iPad, introduced in March 2011. The thinner, faster iPad added two cameras for video calling over Wi-Fi. With a dual-core CPU, faster graphics, a gyro and accelerometer, it was better at gaming than the iPad 1. Three ounces lighter, memory was increased from 256MB to 512MB, but storage capacities remained unchanged (16-64GB). Designed for video calling and printing small photos, the rear-facing camera was only one megapixel, compared to five on other tablets and smartphones. A Digital AV Adapter enabled everything on screen to display on a TV set via HDMI. In the iPad 1, only apps programmed to support an external display would work. See iPad

Much Faster for Games
The faster CPU in the iPad 2 showed up in games such as Real Racing 2 HD. Turning was done by moving the iPad like a steering wheel.
