Mr. Jobs, appearing energized but gaunt, a result of his ongoing health challenges, unveiled the iPad at a press event here on Wednesday morning. Its features and specifications, once the stuff of Internet myth, are now sharply in focus: The half-inch thick, 1.5 pound device will feature a 9.7-inch multi-touch screen and is powered by a customized Apple microchip, which it has dubbed A4. The iPad will have the same operating system as the iPhone and access to its 140,000 applications.
The price of the device will start at $499 for the most basic model, with a Wi-Fi wireless connection. More expensive models will be offered with more memory and with 3G wireless access from ATT, which will charge up to $30 for an unlimited monthly data plan.
