The iPad is a tablet computer designed and developed by Apple. It is particularly marketed for consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. At around 700 grams, its size and weight are intermediate between most contemporary smartphones and laptop computers. Sales of the iPad tablet are strong: since its release in April 2010, Apple has sold 3 million iPads.
The iPad runs the same operating system as the previously introduced iPod Touch and iPhone (initially iPhone OS 3.2, with an update to iOS 4 announced for Fall 2010). Likewise, it is controlled by a multitouch display sensitive to fingertip contact with up to eleven fingers. This is unlike most previous tablet computers which instead used a pressure-triggered stylus. It runs iPad-specific applications as well as those written for the iPhone and iPod Touch, including e-book readers.
The iPad uses Wi-Fi or a 3G mobile data connection to browse the Internet, load and stream media, and install software. A USB cable is required to sync the iPad with iTunes on a personal computer, by which the device is managed.
