The original iPad that started the trend is a model that most notably features a 9.7-inch multi-touch glossy LED-backlit display and the same operating system that powers the iPhone and iPod touch models. As a result it is compatible with many apps for the iPhone/iPod touch, but not Mac OS X. It can sync with a Mac or PC like an iPhone, but has the option to be used as a laptop with a Bluetooth keyboard and mouse.
