The iPad Mini (stylized as iPad mini) is the first generation, known retrospectively as the iPad Mini 1, of the mini tablet computer designed, developed, and marketed by Apple Inc. It was announced on October 23, 2012, as the fourth major product in the iPad line and the first of the iPad Mini line. It features a reduced screen size of 7.9 inches (20 cm), compared to the 9.7-inch (25 cm) display on standard iPads at that time. Its internal specifications resemble that of the iPad 2, including its display resolution. The first generation iPad Mini received positive reviews, with reviewers praising the device's size, design, and availability of applications. However, reviewers criticized its use of a proprietary power connector, its lack of expandable storage, its under-powered Apple A5 chip with 512 MB RAM, and the lack of a Retina display. The first generation iPad Mini was succeeded by the iPad Mini 2.
