Apple's first tablet computer was the Newton MessagePad 100,[15][16] introduced in 1993, which led to the creation of the ARM6 processor core with Acorn Computers. Apple also developed a prototype PowerBook Duo-based tablet, the PenLite, but decided not to sell it in order to avoid hurting MessagePad sales.[17] Apple released several more Newton-based PDAs; the final one, the MessagePad 2100, was discontinued in 1998.strategy is really simple. What we want to do is we want to put an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes ... And we really want to do it with a radio link in it so you don’t have to hook up to anything and you’re in communication with all of these larger databases and other computers.[14]
Apple re-entered the mobile-computing markets in 2007 with the iPhone. Smaller than the iPad, but featuring a camera and mobile phone, it pioneered the multitouch finger-sensitive touchscreen interface of Apple's iOS mobile operating system. By late 2009, the iPad's release had been rumored for several years. Such speculation mostly talked about "Apple's tablet"; specific names included iTablet and iSlate.[18] The actual name is reportedly a homage to the Star Trek PADD, a fictional device very similar in appearance to the iPad,[19] as well as being a variation of the word "iPod". The iPad was announced on January 27, 2010, by Jobs at an Apple press conference at the Yerba Buena Center for the Arts in San Francisco.[20][21]
Jobs later said that Apple began developing the iPad before the iPhone,[22][23] but temporarily shelved the effort upon realizing that its ideas would work just as well in a mobile phone.[24] The iPad's internal codename was K48, which was revealed in the court case surrounding leaking of iPad information before launch.[25]
Apple began taking pre-orders for the first-generation iPad from American customers on March 12, 2010.[3] 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 from sound muting to that of a screen rotation lock.[26] The Wi-Fi version of the iPad went on sale in the United States on April 3, 2010.[3][27] The Wi-Fi + 3G version was released on April 30.[3][4][4] 3G service in the United States is provided by AT&T and was initially sold with two prepaid contract-free data plan options: one for unlimited data and the other for 250 MB per month at half the price.[28][29] On June 2, 2010, AT&T announced that effective June 7 the unlimited plan would be replaced for new customers with a 2 GB plan at slightly lower cost; existing customers would have the option to keep the unlimited plan.[30] The plans are activated on the iPad itself and can be canceled at any time.[31]
The iPad was initially only available online at the Apple Store as well as the company's retail locations, but has since become available for purchase through retailers including Amazon, Walmart, and network operators. The iPad was launched in countries including Australia, Canada, France, Germany, Japan and the United Kingdom on May 28.[32][33] Online pre-orders in those countries began on May 10.[4] Apple released the iPad in Hong Kong, Ireland, Mexico, New Zealand and Singapore on July 23, 2010.[34][35][36] Israel briefly prohibited importation of the iPad because of concerns that its Wi-Fi might interfere with other devices.[37] On September 17, 2010, the iPad was officially launched in China.[38]
300,000 iPads were sold on their first day of availability.[39] By May 3, 2010, Apple had sold a million iPads,[40] this was in half the time it took Apple to sell the same number of original iPhones.[41] After passing the one million mark they continued selling rapidly reaching 3 million sales after 80 days.[42] During the October 18, 2010, Financial Conference Call, Steve Jobs announced that Apple had sold more iPads than Macs for the fiscal quarter.[43] In total, Apple sold more than 15 million first-generation iPads prior to the launch of the iPad 2.[44] — selling more than all other tablet PCs combined since the iPad's release.[45] and reaching 75% of tablet PC sales at the end of 2010.[46]
Jobs unveiled the iPad 2 at a March 2, 2011, press conference.[47][48] 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 videophone application, as well as a three-axis gyroscope. It retains the original's 10-hour battery life and has a similar pricing scheme.
The successor to the iPad 2 was unveiled on March 7, 2012 by Apple CEO Tim Cook at the Yerba Buena Center for the Arts.[49][50] The new iPad sports the new dual core A5X processor with quad-core graphics, and a Retina Display with a resolution of 2,048 by 1,536 pixels[51] this is over 50 percent more pixels than a standard 1,920 by 1,080 high definition TV screen. As with previous iPads, there are two models, in this case a Wi-Fi only model and a Wi-Fi + Cellular model.[51]
On October 23, 2012, Apple announced the fourth generation of the iPad, expected to start shipping on November 2, 2012. The new hardware includes an A6X processor, HD FaceTime camera, improved LTE compatibility, and the all-digital Lightning connector. It will be available in the same storage increments and pricing structure as the third generation.[52][53] Following the announcement of the fourth-generation iPad, the previous generation was discontinued.
On October 23, 2012, Apple announced the iPad Mini. With a screen measuring 7.9 inches, it is aimed at the emerging sector of smaller tablets such as the Kindle Fire. The hardware of the new iPad Mini is similar to the iPad 2, with a 1024 by 768 pixel resolution screen, and with a dual core A5 processor, but 53% lighter and 7.2mm thick. It is scheduled to be released on November 2, in 16GB, 32GB, and 64GB capacities. There are both WiFi and 4G versions, starting at $329 and $459 respectively.[53]
