During the keynote, Apple claims that iPhone 5 is the thinnest phone in the world, and that made me wonder: Is it thinner than the Droid Razr? The Droid Razr is 7.1 mm (0.28 in) thick, while the iPhone 5 is 7.6 mm thick. Was Apple claiming that iPhone 5 is the thinnest phone in the world just a marketing gimmick? Or do they actually research this stuff?
