The third device in the iPad line of tablets, it added a Retina display, the new Apple A5X chip with a quad-core graphics processor, a 5 megapixel camera, HD 1080p video recording, voice dictation, and support for LTE networks in North America.〔(【引用サイトリンク】title=Apple iPad 3 Wi-Fi + 4G )〕 It shipped with iOS 5.1, which also provides a platform for audio-visual media, including electronic books, periodicals, films, music, computer games, presentations and web content.〔 In the US and Canada, nine variations of the third-generation iPad were offered, compared to six in the rest of the world, although some countries had only the Wi-Fi only model. Each variation was available with black or white front glass panels, with options for 16, 32, or 64 GB of storage. In North America, connectivity options were Wi-Fi only, Wi-Fi + 4G (LTE) on Verizon, AT&T, Telus, Rogers, or Bell. For the rest of the world outside North America, connectivity options are Wi-Fi only (on the Wi-Fi model) or Wi-Fi + 3G (on the Wi-Fi + Cellular model), with the latter unavailable in some countries, as 4G (LTE) connectivity for the device is not available outside North America. The Wi-Fi + Cellular model includes GPS capability. Initially, the cellular version was titled and marketed worldwide as the "Wi-Fi + 4G" model, but due to lack of 4G (LTE) connectivity outside of North America, Apple later rebranded and altered their marketing to call this the "Wi-Fi + Cellular" model.〔〔〔 The tablet was released in ten countries on March 16, 2012.〔 It gained mostly positive reviews, earning praise for its Retina display, processor and 4G (LTE) capabilities.〔〔〔〔〔 However, controversy arose when the LTE incompatibilities became known. Three million units were sold in the first three days.〔 After only 221 days of official availability, the third-generation iPad was discontinued on October 23, 2012, following the announcement of the fourth generation iPad. ==History== Speculation about the product began shortly after Apple released the iPad 2, which featured front and back cameras as well as a dual-core Apple A5 processor. Speculation increased after news of a 2,048 by 1,536 pixel screen leaked. During this time, the tablet was called the "iPad 3", a colloquial name sometimes still used after the release. On February 9, 2012, John Paczkowski of All Things Digital stated that "Apple’s not holding an event in February – strange, unusual or otherwise. But it is holding one in March – to launch its next iPad." Another common rumor at the time was that the tablet would have an Apple A6 processor. On February 29, 2012 Apple announced a media event scheduled for March 7, 2012 at the Yerba Buena Center for the Arts. The company did not predisclose the subject of the event, but analysts widely expected the event to announce a new version of the iPad. The announcement affected the tablet resale market positively. At the event, Apple CEO Tim Cook introduced iOS 5.1, a Japanese version of Siri, and the third generation Apple TV before the third-generation iPad. Cook claimed that the new product would be one of the main contributors to the emerging "post-PC world" – a world in which digital life would not be tied to the PC. The March 16, 2012 release included eight countries including Australia, Canada, Japan, Singapore, the United Kingdom and the United States. The March 23, 2012 release included many European countries, Mexico and Macau.〔 The April 20, 2012 release added a dozen countries including South Korea and Malaysia. The April 27, 2012 release added nine more countries, including India and South Africa. May 2012 releases added 31 countries, including Brazil and Turkey. On October 23, 2012, upon the announcement of the fourth-generation iPad, the third-generation iPad was discontinued. In response to criticism from its owners, the return policy of select Apple Stores was briefly extended to thirty days to allow customers to exchange the third generation model for the fourth generation model. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IPad (3rd generation)」の詳細全文を読む スポンサード リンク
