Apple uses the same 7.9-inch, 2, 048-by-1, 536-pixel IPS LCD featured on the mini 2. Its an undeniably high-quality panel thats towards the top in terms of brightness and sharpness, but it doesnt benefit from the same optical bonding or anti-reflection upgrades that come with the iPad Air 2. It also doesnt impress quite like the Tab S 8.4s 2, 560-by-1, 600-pixel AMOLED display, with its infinite contrast, incredible max brightness, and vibrant colors. There are two new features of note for the mini 3: Touch ID and Apple SIM. The former is familiar at this point, having debuted with the iPhone 5s last year. It works with the same reliability and ease weve come to expect. Then theres Apple SIM, which lets you use a single SIM card regardless of which carrier you choose to use for cellular data. Instead of having to go to the store and replace your SIM card, you can go straight into the Cellular Data settings menu and add a new account for your desired carrier. While useful, its more of a niche play—Id be curious to see what percentage of tablet users switch their carriers on a regular basis.
