Weighing in at just one pound, the 9.8-inch Apple iPad Air is the lightest full-size iPad to date. It's also 20% thinner than the fourth-generation iPad, and comes with the same Apple A7 chip as the iPhone 5S and iOS 7 as standard. Otherwise it's very much the same as the previous model, with a 264ppi screen and a 5-megapixel camera on board. Pricing for the Wi-Fi only model starts at $499 for the 16GB variant. The Wi-Fi + cellular model has SRPs starting at $629 (again for the 16GB version). Both the Wi-Fi only and Wi-Fi + cellular configurations will be available in 32GB, 64GB and 128GB capacities as well, starting 1 November 2013.
