It features multi-touch interaction with print, video, photo, and audio multimedia, internet browsing, and runs most iPhone OS apps. The device has an LED-backlit 9.7-inch colour LCD display and uses a virtual keyboard for text input, although one of the optional accessories offered by Apple is an iPad keyboard dock.
