Apple has officially introduced the newest edition of its full-sized tablet today with the debut of iPad Air 2. Touch ID, first seen in iPhone 5s and included within iPhone 6 and iPhone 6 Plus, has been added to the tablet. The side switch has been removed, and it appears to have been replaced by another microphone.

iPad Air 2 is 6.1 mm thin, 18 percent thinner than the previous iPad Air. A single-component display reduces internal reflection with a sharper image.
The screen also now has an anti-reflective coating, and reflections are reduced by 56 percent.
A new chip, A8X, has been created specifically for iPad Air 2. The second-generation 64-bit architecture chip is 40 percent faster. The GPU is 2.5x faster than iPad Air. iPad Air 2 has 10-hour battery life and an M8 coprocessor that can track elevation and motion.
A new iSight camera has been added to the new Air — an 8MP camera that can shoot 1080p HD video. Burst mode is also available on the iPad Air 2 camera. Slo-mo videos have also been added to video recording — 120 fps at 720p. A new FaceTime camera with an all new sensor has also been included in iPad Air 2 — improved face detection, burst selfies, HDR videos, and single-shot HDR photos are all included.
Faster Wi-Fi — 802.11 ac with MIMO — and faster LTE with 20 LTE bands are featured in iPad Air 2.
