A full-sized tablet that only weighs 1 pound? That's the design feat Apple accomplished with the iPad Air. And it's thin too, measuring in at a depth of .29 inches. Apple claims its latest innovation is the lightest full-sized tablet on the market. In comparison, both Apple's iPad 2 and Lenovo's new Yoga Tablet 10 weigh in at 1.33 pounds, whereas the Samsung Galaxy note comes in at approximately 1.2 pounds.
