Apple's first iPad was unveiled in 2010 with a 9.7-inch multitouch display, making it a more capable device than its predecessor. The iPad 2 launched in 2011 with basic front and rear cameras, enabling the launch of future camera technology in subsequent iPad models. The first iPad Pro launched in 2012 with a compact model that fit between the iPhone and the standard iPad, and later the iPad Air (2013) brought 64-bit computing to the lineup with the A7 chip. In 2015, Apple introduced the first high-end iPad Pro, aimed at professionals and creatives who required more power and screen real estate. The company has also been using this platform for launching new technologies, such as the 2018 iPad Pro with an edge-to-edge design and the replacement of Touch ID with Face ID. Other notable milestones include the introduction of Sidecar alongside iPadOS 13 and macOS 10.15, allowing Mac owners to use a nearby iPad as a wireless secondary display. In 2021, an iPad Pro equipped with the Mac’s M1 chip will be prepared for more advanced upgrades.
