The device was released five years after the previous fourth-generation iPad. as the iPad Air was released in 2013 as the successor to the iPad lineup. The iPad Air lineup later continued as a separate, higher-end device, while the iPad was positioned as an entry-level model.
This iPad model was announced by Apple on March 24, 2017 in a press release.[5][6][7] There has been confusion around its naming, being referred to as just "iPad" in marketing,[6] but called the "fifth-generation iPad" in official statements and specifications sheets,[8][3] a title previously taken by 2013's iPad Air.[9][10] Other sources refer to it as the "seventh-generation iPad",[11] when including the iPad Air and iPad Air 2 as the fifth- and sixth-generation iPads respectively.[12] It has also been referred to as "iPad 2017".[13][14][15]
Matt Kapko of CIO wrote that Apple's introductory pricing of $329 in the United States for the iPad, a $70 price reduction vs the iPad Air 2, appeared to be designed to fend off the encroachment of Google's Chromebook laptops in the education sector and to foster wider adoption in customer-facing terminals. Kapko also wrote that the device is designed to appeal to businesses that require inexpensive tablets for undemanding use, including as kiosks, checkout terminals, and hospitality screens.[16]
The fifth generation iPad shares most design elements with the iPad Air, with a 9.7-inch (25 cm) screen,[2] 7.5 mm (0.30 in) thickness,[17][7] and differences such as the lack of the physical mute switch, smaller microphone holes and only a single row of speaker holes, and storage.[18][19] Compared to the iPad Air 2, the processor is updated from the Apple A8X to the A9 with the embedded Apple M9 motion co-processor.[20] The fifth generation iPad has 2 gigabytes of RAM.[2] Unlike other iPad models available, this iPad's display is not fully laminated and does not have anti-reflective coating.[6][21] However, this iPad has a brighter screen than the iPad Air 2 (25% brighter according to Apple).[22] It is available in 32 and 128 GB[a] storage options.[23] Contrasting with the iPad Pro lineup, this iPad features only two speakers (as opposed to four), has no Smart Connector support, and has no camera flash.[13] It is offered in silver, gold, and space grey colors.[13] Despite its use of the Apple A9 processor and accompanying M9 motion co-processor, introduced with the iPhone 6S in 2015, the iPad does not feature support for always-on "Hey Siri" voice input, a feature advertised as being made possible by low-power processing in the then-new chips. The use of "Hey Siri" is limited to when the iPad is connected to power.[24]
At the time of its original release, the iPad shipped with iOS 10, a version of Apple's mobile operating system.[5] New units sold come with the new iOS 11 operating system after its Fall 2017 release.[25] The included Touch ID fingerprint sensor allows the user to unlock the device as well as approve purchases from the App Store, iTunes Store, and Apple Books Store. Touch ID and Apple Pay let the user purchase items from websites or from within apps.[5][6]
The iPad received generally positive reviews. It was significantly praised for performance, with reviewers asserting that the model was noticeably faster than older iPad models, and also received positive reviews for its price and battery life. It was criticized, however, for lacking a laminated and anti-reflective screen, lack of support for the Apple Pencil, and lack of a Smart Connector for accessories such as attachable keyboards, the latter two of these criticisms being remedied with the introduction of the iPad (6th generation) a year later. Its introductory price in the United States was the lowest ever for an iPad, with the media noting that the lower price might be an effort to encourage wider adoption of the tablet in the education sector, as well as for businesses needing inexpensive tablets for undemanding uses.
Dieter Bohn of The Verge wrote that "it is a thin, fast tablet", and praised the screen for being "very good", despite not having "the fancy True Tone display that the iPad Pro does, nor does it have some of the things that made the screen on the iPad Air 2 so nice: lamination and anti-reflectivity". He criticized the lack of support for attachable keyboards and Apple Pencil, while praising the A9 processor as "significantly faster than older iPads", though noting that it isn't "necessarily significantly faster than the iPad Air 2", and "not as fast as the iPad Pro". He also disliked that the iPad only features two speakers, as opposed to four on the iPad Pro, while summarizing the overall review with "Fundamentally, what I am trying to tell you is that this is an iPad. You trust that iPads are decent tablets and that they have a basic level of quality, speed, and functionality" and "Get one if you need one, but don't stress that you're missing out if you don't."[27]
Sascha Segan of PC Magazine wrote that "The Apple iPad is more affordable than ever" and noted that "While there's little reason for existing iPad owners to upgrade, the new iPad's price stabs a stake into the heart of many competing Android tablets". Although criticizing the non-laminated display for being "a little more washed out than its predecessor", he claimed that he "couldn't see a measurable difference" and that it's "a nominal degradation in quality that doesn't really matter in everyday use". Segan also praised performance compared to the prior iPad models, and also praised improved Wi-Fi performance, writing that it is "quite impressive" with "double the Wi-Fi speeds on the new iPad than I did on the Air 2".[28] Jeff Benjamin of 9to5Mac wrote that "Sure, it lacks the gorgeous laminated, anti-reflective display of the iPad Air 2, and sure it's not as svelte in either thickness or weight. But there's no denying that the 2017 iPad with A9 dual core processor in tow, is a good value". He described the tablet as a "solid buy for upgraders and new users".[29]
Igor Bonifacic of MobileSyrup also praised the performance, as well as number of iPad apps available, but criticized the camera for being outdated and keyboard/Pencil incompatibility, with a summarization reading: "The 2017 iPad is not an exciting tablet. But then it's not supposed to be exciting, [...] Apple's latest tablet is an iterative update designed to appeal to a specific subset of consumers". Bonifacic also called the tablet "perfect for first-time tablet buyers".[30] Chris Velazco of Engadget praised battery life, describing it as "one of the best iPads we've tested", but also criticized the lack of anti-reflection on the display, calling it "another cost-saving measure that I wish Apple had reconsidered".[31]
Apple CEO Tim Cook finally showed the world the iPad Mini on Tuesday, capping off months of hearsay and speculative blog posts. Critics who briefly got to try it out generally came away with positive first impressions. "From a hardware standpoint, the iPad Mini is the nicest of the smaller tablets out there," says Joanna Stern at ABC News. At 7.9 inches, it's as thin as a pencil and lighter than a pad of paper, perfectly replicating the user experience of its full-sized sibling. One number, however, raised a few critics' eyebrows: The device's $329 starting price tag, which is a full $130 higher than the direct competition. Apple marketing head Phil Schiller defended the decision, claiming that consumers are willing to pay for quality not found in Amazon's Kindle Fire HD or Google's Nexus 7. Does he have a point? Or will erstwhile Apple consumers see the price differential and go with a $200 tablet instead?
The Mini is way too expensive: The iPad Mini is "certifiably overpriced," says Brian Barret at Gizmodo. When you look at it next to the Kindle Fire HD and the Nexus 7, "you get the impression it's a pretty level playing field," at least specification-wise. Essentially you're paying a 65 percent premium "for a device that's not decidedly better in any way other than size and apps." The real genius of the first iPad was that it wasn't just first, it was the cheapest, too. "Charging so much more for a product that's not clearly so much better is a major step backwards for Apple, especially given its unfamiliar position in the small tablet space."
So my question is : did apple published all the multi-touch apis first then W3C followed apple to make all the specifications? or did W3C published the specifications first then apple followed the specifications to make a new version of Safari?
3.If I write a web page that uses multi-touch to interact with users, can the users be able to use this web page in IPad, Android devices and Windows Phone 7(Mango)?Or do I have to write different code for each different platform?
The Touch Events Specification is based on events cloned from Apple Safari's implementation, although it adds significantly to it. It is not technically part of HTML5. The other platforms have also copied Safari's touch events. It should be possible to write code to the original Apple Safari reference documentation and have it work on iPad and Android. I don't know about Windows Phone 7 (Mango).
