Trackpad Support
Apple has highlighted this as a feature of the new iPad Pro, but in reality this is a software feature that will come to all iPad models as part of iPadOS 13.4. In fact, Apple’s new Magic Keyboard is expected to be compatible with the older 2018 iPad Pro models, and we’re already seeing third-party keyboards that include trackpads for the iPad and iPad Air.
Further, users will also be able to connect a Magic Trackpad, Magic Mouse, or likely any wireless mouse or track over Bluetooth to take advantage of the new capabilities, and it seems likely even USB mice (either directly via USB-C or via Apple’s USB-to-Lightning connector) will work too.
As 9to5Mac describes it, the new system isn’t exactly like a PC or Mac mouse pointer, however, but rather a “hybrid between a typical mouse pointer seen on a desktop operating system and the focus engine system used in Apple TV.” The trackpad support will also offer Mac-like gesture support for things like switching apps and bringing up the Dock and Control Center.
