The iPad is a tablet computer developed by Apple Inc. It is scheduled to be released in March 2010 (WiFi-only models) and April 2010 (WiFi + 3G models). It will feature multi-touch interaction with print, video, photo, and audio multimedia, internet browsing, and will run apps designed specifically for the iPad as well as most iPhone OS apps.The device will have an LED-backlit 9.7-inch (25 cm) color IPS LCD display and use a virtual keyboard for text input.
Apple's development of a tablet computer began with the Newton MessagePad 100, which was introduced in 1993. The effort led to the creation of the ARM6 processor core with Acorn Computers. Apple also developed a prototype PowerBook Duo-based tablet computer named the PenLite, then canceled the project as it was too similar to the Newton line. Apple brought out several more Newton-based PDAs, and discontinued the last of the line, the MessagePad 2100, in 1998.
The iPad featuring the home screen
Apple renewed efforts to develop a tablet as early as 2000. Apple CEO Steve Jobs canceled the project twice, once due to insufficient battery life, and again due to inadequate memory.[citation needed] After returning from medical leave, Jobs devoted most of his attention at Apple to completing the device, striking deals with print media companies before the product's announcement.
The product was announced on January 27, 2010, at an Apple press conference at the Yerba Buena Center for the Arts in San Francisco. The device's imminent release had been rumored for several months with iSlate and iTablet among speculated names
