The Ipad Family are namely Ipad Generation 1-4 , Ipad Air , Ipad Air 2 and the Ipad Pros Which have a smaller cousin the iPad mini 1-4 generation.
The latest 9.7 and 12.9-inch iPad Pro models will look immediately familiar to anyone who has used an iPad Air 2, as both take design cues from Apple's 2014 tablet. The 9.7-inch iPad Pro looks almost identical to the iPad Air 2 while the 12.9-inch iPad Pro looks like a larger version of the iPad Air 2.
The iPad Pro has smooth, rounded edges and a thin bezel around the display, which is thicker at the top and the bottom where the front-facing camera and the home button are located. At the top, there's a sleep/wake button and a headphone jack, and there's a Lightning port for charging at the bottom. On the right side, there are volume control buttons and a microphone hole. For cellular models, the 9.7-inch iPad has thinner outline-style antenna bands similar to the bands on the iPhone 6s.
