apple.com | up to $929 with 128GB: Apple's fifth-generation iPad slims down with the new iPad Air, weighing just 1 pound (down from the fourth generation's 1.44 pounds) and measuring just 7.5 millimeters thick (vs. 9.4 mm). If that's barely noticeable, the new A7 chip and M7 co-processor make it eight-times faster, and render graphics at twice the rate of the previous iPad. The same chip powers the iPhone 5S. A 5-megapixel iSight camera on the rear, and updated FaceTime HD camera, and dual microphones, may not be the dramatic updates the Apple faithful may have wanted. But at 10 hours of battery life, the 9.7-inch iPad Air is a device that packs enough of a punch to still make it the one to beat.
