The 16GB iPad Air from Apple features an even thinner design than its predecessor. Dropping almost a quarter of the volume of the previous generation iPad, the iPad Air is just 0.29" (7.5 mm) thin and weighs just 1.05 pounds. Overall, the iPad Air is 28% lighter, 20% thinner and 24% less volume than the previous iPad. The iPad Air may be thinner and lighter, but it's still durable and solid. That's because it still has an aluminum unibody design.
