) is a line of tablet computers designed, developed and marketed by Apple Inc., which run the i OS mobile operating system.

There have been four versions of the i Pad Mini, all of which have a screen size of 7.9 inches (20 cm).
The first generation has similar internal specifications as the i Pad 2 but uses the Lightning connector instead.
By late 2009, the i Pad's release had been rumored for several years.
As of March 2016, the App Store has more than one million apps for the i Pad by Apple and third parties. The first generation established design precedents, some of which, such as the home button placement, have persisted through all models.Jonathan Ive in 1991 had created an industrial design for a stylus-based tablet, the Macintosh Folio, as his first project for Apple; by 2004 his studio at the company was participating in the development of a large tablet prototype, which he later described as "very crude, involving projectors".Ive stated that after seeking to produce the tablet first, he came to agree with Jobs that the phone was more important, The only major change to the device between its announcement and being available to pre-order was the change of the behavior of the side switch to perform either sound muting or screen rotation locking (user selectable).Apple also developed a prototype Power Book Duo based tablet, the Pen Lite, but decided not to sell it in order to avoid hurting Message Pad sales.Apple released several more Newton-based PDAs; the final one, the Message Pad 2100, was discontinued in 1998.
