The iPad is a tablet computer designed and developed by Apple. It is particularly marketed as a platform for audio and visual media such as books, periodicals, movies, music, and games, as well as web content. At about 700 grams (25 ounces), its size and weight are between those of most contemporary smartphones and laptop computers. Apple released the iPad in April 2010, and sold 3 million of the devices in 80 days.
The iPad runs the same operating system as the earlier iPod Touch and iPhone, albeit a slightly older version. It can run its own applications as well as ones developed 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 — 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. The device is managed and synced by iTunes on a personal computer via USB cable.
Media reaction to the device has generally been neutral or positive, with more positive reaction after the device was launched. Additionally while is aimed at consumers it has also seen uptake by business users.

Storage and SIM
The iPad was released with three options for internal storage size: a 16, 32, or 64 GB flash drive. All data is stored on the flash drive and there is no option to expand storage. Apple sells a camera connection kit with an SD card reader, but it can only be used to transfer photos and videos
The side of the Wi-Fi + 3G model has a micro-SIM slot (not mini-SIM). Unlike the iPhone, which is usually sold locked to specific carriers, the 3G iPad is sold unlocked and can be used with any compatible GSM carrier. Japan is the exception to this, where the iPad 3G is locked to Softbank. In the U.S., data network access via T-Mobile's network is limited to slower EDGE cellular speeds because T-Mobile's 3G Network uses different frequencies.

Optional accessories
Apple offers several iPad accessories, including:
- iPad Keyboard Dock with hardware keyboard, 30-pin connector, and audio jack
- iPad Case which can be used to stand the iPad in various positions
- iPad Dock with 30-pin connector and audio jack
- iPad Dock Connector to VGA Adapter for external monitor or projector
- iPad Camera Connection Kit including a USB Type A connector adapter and an SD card reader, for transferring photos and videos
- iPad 10W USB Power Adapter with 2 A output (10 W)
Applications
The iPad comes with several applications, including Safari, Mail, Photos, Video, YouTube, iPod, iTunes, App Store, iBooks, Maps, Notes, Calendar, Contacts, and Spotlight Search. Several are improved versions of applications developed for the iPhone.
The iPad syncs with iTunes on a Mac or Windows PC. Apple ported its iWork suite from the Mac to the iPad, and sells pared down versions of Pages, Numbers, and Keynote apps in the App Store. Although the iPad is not designed to replace a mobile phone, a user can use a wired headset or the built-in speaker and microphone and place phone calls over Wi-Fi or 3G using a VoIP application. The iPad has lots of third party applications available for it; as of September 1, 2010 there were 25000 iPad specific apps on the AppStore.
Jailbreaking
Like other iOS Devices, the iPad can be "jailbroken", allowing applications and programs that are not authorized by Apple to run on the device. Once jailbroken, iPad users are able to download many applications previously unavailable through the App Store via unofficial installers such as Cydia, as well as illegally pirated applications. Apple claims jailbreaking voids their factory warranty on the device in the United States.
Books, news, and magazine content
Reading a book on the iPad
The iPad has an optional iBooks application that can be downloaded from the App Store, which displays books and other ePub-format content downloaded from the iBookstore. For the iPad launch on April 3, 2010, the iBookstore is available only in the United States. Several major book publishers including Penguin Books, HarperCollins, Simon & Schuster and Macmillan have committed to publishing books for the iPad.
In February 2010, Condé Nast Publications said it would sell iPad subscriptions for its GQ, Vanity Fair and Wired magazine’s by June. In April 2010, The New York Times announced it will begin publishing daily on the iPad.
Major news organizations, such as The Wall Street Journal, BBC, and Reuters have released iPad applications, to varying degrees of success.
