The iPad is a tablet computer designed and marketed by Apple for Internet browsing, media consumption, gaming, and light content creation. Released in April 2010, it established a new class of devices between smart phones and laptops. As of May 3, 2010, Apple had sold 1 million iPads. Similar to the older (and smaller) iPod Touch and iPhone, the iPad runs a modified version of the iPhone OS and is controlled by a multi-touch LCD sensitive to fingertips, not a stylus. It runs iPad-specific applications as well as those written for the iPhone and iPod touch, including e-book readers. The iPad uses WiFi or its 3G 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.
It comes with two mono speakers and a microphone within the device. The iPad is designed to be charged with a high current (2 amperes) using the included USB 10 W power adapter. While it can be charged by a standard USB port from a computer, these typically provide lower current (500 milliamperes or 1 ampere). As a result, if the iPad is turned on while being charged with a normal USB computer port, it will charge much more slowly, if at all.
The iPad was released with three options for internal storage size: a 16, 32, or 64 GB flash drive. All data are 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 Wi-Fi and 3G model has a micro-SIM slot (not mini-SIM) located on the side of the device. The 3G model may be used with an AT&T data plan that does not require a contract. Apple has heavily advertised the uses of the no-contract plan on their website. 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. However it does not support T-Mobile's 3G Network and Verizon does not use world-standard GSM SIM cards
