The Latest Entertainment Device Apple I-Pad.

HISTORY

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 but the project was later canceled, to avoid confusing the market with too many similar devices.Apple brought out several more Newton-based PDAs, and discontinued the last of the line, the MessagePad 2100, in 1998.

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. 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.
