2. iPad 2

The iPad 2 came out in 2011, and brought a camera to the device. With dual-facing cameras, the iPad 2 gave users the ability to take pictures, record movies, and host video chats. The second generation doubled the processing speed, and featured a more powerful graphics processor. This iPad is slightly thinner and lighter than its predecessor, already starting the movement toward Apple's lightweight devices.
