The iPad Air 2 was the first iPad to use Touch ID. It was announced at an October 2014 Apple event titled, “Change Is in the Air.” This iPad was available in three colors: gold (gold aluminum back with a white glass front), silver (silver aluminum back with a white glass front), and space gray (dark gray aluminum back with a black glass front).
The 9.7-inch touchscreen Retina Display was 2048×1536 (at 264 ppi) and featured an antireflective coating. Internally, it used a three-core 1.5 GHz A8X processor, 2 GB of RAM, and was available with 16, 32, 64, or 128 GB of storage.
Its rear 8-megapixel iSight camera recorded video at 1080p (30 fps), and its front 1.2-megapixel FaceTime HD camera recoded video at 720p.
The original iPad Air used a 9.7-inch Retina display. According to Apple’s press release at the time, the iPad Air was “20 percent thinner and 28 percent lighter than the fourth generation iPad, and with a narrower bezel the borders of iPad Air are dramatically thinner.”
The original iPad Air’s display was 2048×1536 (at 264 ppi). Internally, it used a dual-core 1.4 GHz A7 processor, 1 GB of RAM, and was available with 16, 32, 64, or 128 GB of internal storage. Wireless connectivity included 802.11a/b/g/n Wi-Fi and Bluetooth 4.0.

The original Apple Pencil was released along with the original iPad Pro in September 2015. The Apple Pencil can be used by the iPad Air (Generation 3), iPad mini (Generation 5), iPad Pro 10.5-inch, iPad (Generation 6 and 7), iPad Pro 12.9-inch (Generation 1 and 2), and iPad Pro 9.7-inch. It pairs to an iPad device using Bluetooth, and has a removable magnetically attached cap hiding a Lightning connector.
The original Apple Pencil somewhat awkwardly charges by plugging it into the lightning port of an Apple device; however, it also includes a female-to-female adapter that allows charging with a Lightning cable. While a full charge can last up to 12 hours, a 15-second charge provides about 30 minutes of use.
The Apple Pencil can be used for writing, drawing, or annotating in a wide variety of apps. Apple describes its features as having “pixel-perfect precision, tilt and pressure sensitivity, and imperceptible lag.”
