Second generation
Apple's CEO Steve Jobs unveiled the iPad 2, the second generation of the device, at a March 2, 2011, press conference, despite being on medical leave at the time. About 33% thinner than its predecessor and 15% lighter, the iPad 2 has a better processor, a dual core Apple A5 that Apple says is twice as fast as its predecessor for CPU operations and up to nine times as fast for GPU operations. The iPad 2 includes front and back cameras that support the FaceTime video calling application, as well as a three-axis gyroscope. It retains the original's 10-hour battery life and has a similar pricing scheme. The iPad 2 has been available for purchase, depending on stock availability, since March 11, 2011, at Apple retail stores in the United States, as well as to American customers shopping online at Apple's retail website. The iPad 2 was released internationally in 25 other countries on March 25, 2011, including Australia, Canada, France, Germany, Mexico and the United Kingdom, but not Japan as originally scheduled due to the earthquake and tsunami. Apple sent invitations to journalists on February 23, 2011 for a media event on March 2. On March 2, 2011, CEO Steve Jobs unveiled the device at the Yerba Buena Center for the Arts, despite being on medical leave. Apple began selling the iPad 2 on its website on March 11, and in its U.S. retail stores at 5 pm local time on that date. Many stores in major cities, such as New York, sold out within hours. Online shipping delays had increased to three to four weeks on Sunday and four to five weeks by Tuesday. The iPad 2 was released internationally in 25 other countries on March 25, 2011. The countries included Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Italy, Ireland, Hungary, Luxembourg, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom. It was later released in Hong Kong, Japan, South Korea, Singapore, Malaysia and other countries on April 29, 2011. The March 25 release date for Japan was postponed due to the earthquake and tsunami which struck the nation on March 11, 2011. The iPads were delayed due to the NAND flash storage chip used in the iPads being created by Toshiba, which was affected by the earthquake and tsunami thus resulting in the suspension of operations for an indefinite period of time. The slowdown caused analysts to downgrade Apple's stock. The 32 and 64 GB models were discontinued on March 7, 2012 upon the introduction of the third generation iPad. The 16 GB Wi-Fi and 16 GB Wi-Fi + 3G models are still in production.
