What is iPad?

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 about 700 grams, its size and weight are between most contemporary smartphones and laptop computers. Apple sold 3 million iPads in the first 80 days after its April 2010 release.

The iPad runs the same operating system as the previously introduced iPod Touch and iPhone, although as of summer 2010, it was a version behind: iOS 3.2.1, with an update to iOS 4 expected in fall 2010. It can run its own specific applications as well as those developed originally for the iPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.

Like iPhone and iPod Touch, the iPad is controlled by a multitouch display sensitive to up to eleven fingers — a break from most previous tablet computers, which used a pressure-triggered stylus. 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.

Media reaction to the device has generally been neutral or positive, with more positive reaction after the device was launched.
