The original Wi-Fi only Apple iPad (1st Gen/A1219) is a tablet computer designed for "browsing the web, reading and sending e-mail, enjoying photos, watching videos, listening to music, playing games, reading e-books, and more".
It is equipped with a 9.7-inch (1024x768, 132 ppi) multitouch "glossy" LED-backlit IPS display and runs a version of the same operating system that powers the iPhone and iPod touch models (originally iPhone OS 3.2, Build 7B367). As a result it is compatible with many apps for the iPhone/iPod touch, but not Mac OS X. It also syncs with a Mac or PC like an iPhone or iPod touch, but can be used like a computer with a Bluetooth keyboard or keyboard "dock" as well.
It is powered by a custom-designed 1 GHz Apple A4 "system on a chip", has 16 GB, 32 GB, or 64 GB of flash memory, 802.11a/b/g/n Wi-Fi support, an accelerometer, ambient light sensor, digital compass, dual mono speakers and a built-in mic packed in a 0.5 inch thick, 1.5 pound glass and aluminum case.
