Boasting a 9.7-inch screen, the slick tablet is slimmer and faster than its predecessor and also marks the addition of the Touch ID fingerprint scanner on the home button. The maker also added a gold version of the gadget for the first time. While still popular, the iPad Air 2 has been joined by a new flagship model – the super-sized iPad Pro – which sports a massive 12.9-inch screen and was released in November 2015.
