Though the 5th-gen iPad is thinner and lighter, Apple managed to cram a slew of improvements making it their best iPad ever. The new iPad Air brings 64-bit desktop-class architecture equipped with A7 chip, increasing its processing power, graphics performance and battery life. In addition, the iPad Air also has a better 5.0 megapixel iSight camera with 1080p video support, a high-def FaceTime camera, dual antennas and microphones, and a M7 motion coprocessor.
