The iPad 4 is a tablet computer and fourth generation of iPad designed and manufactured by Apple Inc. It was released in the United States on November 2, 2012, and continued to be released throughout December in other countries such as China and Brazil. During the first weekend of sales, over three million iPad 4s were sold. The release of the iPad 4 caused the discontinuation of the iPad 3. On January 29, 2013, Apple announced that they were launching a 128 GB variant of the iPad 4. It was released a few days later on February 5, 2013.
The iPad 4 shipped with iOS 6.0 as well as several pre-installed applications, such as Siri, Mail, Safari, iTunes, Appe Store, Maps, Calendar, and Game Center. It can act as a hotspot with certain carriers, sharing its Internet connection over Bluetooth, Wi-Fi, or USB and provides access to the Apple App Store. The iPad 4 can sync content and other data with a PC or Mac using iTunes, although iOS 5 and higher can be managed without a computer. People can use headsets or the microphone and speaker to make phone calls over Wi-Fi using a VolP application (e.g. Skype). The iPad 4 also has voice recognition technology (same as the iPhone 4S), allowing users to give voice commands to the iPad 4. The iPad 4 also has an iBooks application, which shows books and other content downloaded from the iBookstore. Barnes & Noble and Amazon both offer e-reader apps for the iPad 4. The Retina display on the device features a 2048 by 1536 resolution and rich color saturation. It also offers an astounding 3.1 million pixels, which is a million more pixels than an HDTV has. The new A6X chip inside the iPad 4 offers up to twice the graphics and CPU performance of the previous chip, and makes the iPad 4 feel more responsive and much faster. The iPad 4 can be purchased from Amazon. The Apple Store offers the 16GB for $500, the 32GB for $600, the 64GB for $699, and the 128GB for $799.
The iPad 4 is 9.50 inches by 7.31 inches and is 0.37 inches thick. It weighs 1.46 pounds. It offers LED-backlit IPS LCD with a multi-touch screen and 16M colours. It has scratch-resistant glass and oleophobic coating. It comes in 4 sizes: 16GB, 32GB, 64GB, and 128GB, and has 1 GB RAM. It also comes in either black or white. Its standby time lasts approximately 720 hours and it has 9 hours of talk time. It has a non-removable Li-Po 11.560 mAh battery.
