- Record Sales: 300,000 iPads 1st generation were sold on their first day of availability on the market and by May 3, 2010, Apple sold a million iPads, that’s in half the time it took Apple to sell the same number of first-generation iPhones. Three million sales were reached after 80 days.On October 18, 2010, Steve Jobs announced that Apple had sold more iPads than Macs for the fiscal quarter. In total, Apple sold more than 15 million first-generation iPads.

All iPads on Earth
- Best Invention of 2010: The iPad was selected by Time magazine as one of the 50 Best Inventions of the Year 2010.
- Screen Rotation: The iPad’s built-in applications support screen rotation in all four orientations, including upside-down. Consequently, the iPad has only the relative position of the home button changes, but no intrinsic native orientation. By the way, the iPhone and iPod Touch’s built-in applications, work in three orientations, that’s portrait, landscape-left and landscape-right.
- Physical Switches: There are four physical switches on the iPad: a home button located near the display (this button returns the user to the main menu), and three plastic physical switches on the sides: wake/sleep, volume up/down, a software-controlled switch. This switch used to lock the screen to its current orientation. Since iOS 4.2 was introduced, it became a mute switch, and rotation lock has been transferred to the onscreen menu. With the arrival of the iOS 4.3, released with the iPad 2, a new setting was added to allow users to specify whether the side switch was used for rotation lock or mute.
- Cameras: The iPad cameras (front and rear) shoot photo and video in a 4:3 fullscreen aspect ratio, unlike the iPhone 4, which shoots in a 16:9 widescreen aspect ratio. The iPad does not support tap to focus, but does allow a tap to set auto exposure.
- Ethernet and USB Port: The iPad has a headphone jack and a proprietary Apple dock connector, but no Ethernet or USB port. The Apple Camera Connection Kit accessory provides two dock connector adapters for importing photos and videos via USB and SD memory cards.
- Apps for iPad: The iPad comes with many applications, including Safari, Mail, Photos, Video, iPod, iTunes, Maps, App Store, iBooks, Notes, Calendar, Contacts. Many of these apps are improved versions of applications developed for the iPhone or Mac. There are abut half a million of iPad specific apps on the App Store. In December 2010, some iPhone and iPad users have lodged a lawsuit against Apple alleging that some applications were passing their information to third party advertisers without consent.
- Audio output: The iPad has two internal speakers reproducing left and right channel audio. In the original iPad, the speakers push sound through two small sealed channels leading to the three audio ports carved into the device,while the iPad 2 has its speakers behind a single grill. A 3.5-mm TRRS connector audio-out jack on the top-left corner of the device provides stereo sound for headphones with or without microphones and/or volume controls. Besides, the built-in Bluetooth 2.1 + EDR interface allows wireless headphones and keyboards to be used with the iPad. The device has a microphone that can be used for voice recording.
- Video output: iPad also features 1024×768 VGA video output for limited applications and screen capture, connecting an external display or television through an accessory adapter.
- iPad Software: iPad shares a development environment with iPhones. The iPad only runs its own software, which can be downloaded from Apple’s App Store. They can also use software written by developers who have paid for a developer’s license on registered devices.
- iPhone Applications: The iPads run almost all third-party iPhone applications. These apps are displayed at iPhone size. They also may be enlarged to fill the iPad’s screen. Developers may also create apps for iPads or modify existing apps to take advantage of the iPad’s features. Application developers use iOS SDK for developing applications for iPad.
- Battery: The internal rechargeable lithium-ion polymer (LiPo) batteries are made in Taiwan either by Simplo Technology or Dynapack International Technology. The iPad is charged with a high current of 2 amperes using the included 10 W USB power adapter and USB cord with a USB connector at one end and a 30-pin dock connector at the other end. The iPad can be charged by a standard USB port from a computer, but in this case it is limited to 500 milliamperes (0.5 amps). As a result, if the device is running while powered by a normal USB computer port, it may charge very slowly, or not at all. However newer Apple computers and accessories have high-power USB ports and can provide thus full charging capabilities.
- Battery Life: Like any rechargeable battery technology, the iPad’s battery loses capacity over time. It can’t be replaced by the user. Apple will replace an iPad that does not hold an electrical charge with a refurbished iPad for a fee. As a refurbished unit is supplied, user data is not preserved, and the refurbished iPad comes with a new case. The warranty on the refurbished unit varies. Independent companies also provide a battery replacement service. Alternatively it is possible for a technically competent user to buy and install a new battery, but the task technically challenging.
- iPad Adapters: Each generation of iPad requires a corresponding dock. A dock that included a physical keyboard was only supported for the original iPad. All iPad generations are compatible with Bluetooth keyboards that also work with Macs and PCs. The iPad can be charged by a standalone power adapter (wall charger) also used for iPods and iPhones. A 10 W charger is included with the iPad.
- Apple Connection Kit: Apple sells a camera connection kit that consists of two adapters for the dock connector. One of them uses USB Type A, the other an SD card reader. Adapter can be used to transfer photos and videos and to plug USB audio card or MIDI keyboard.
- Third Party Connection Kit: Third parties sell an adapter that includes USB, SD, and microSD on a single unit. An adapter to VGA connectors allows the iPad to work with external monitors and projectors. Another adapter mirrors the screen onto HDMI compatible devices in 1080p and works with all apps and rotations. It allows the iPad to charge through another dock connector.
- HDMI Adapter: While the HDMI adapter was released for the second generation iPad, it also works with the first-generation iPad, the iPhone 4, and the fourth generation iPod touch.
- Smart Covers: Smart covers are screen protectors that magnetically attach and align to the face of the iPad 2, 3, or 4. The Smart cover has three folds which allow it to convert into a stand, which is also held together by magnets. The Smart Cover is easily detachable. It has a microfiber bottom that cleans the front of the device, which wakes up when the cover is removed. The Smart covers are sold in five different colors of both polyurethane and leather(leather being more expensive). Smart Covers are not compatible with the original iPad.
- Smart Case: In June 2012, Apple started selling the Smart Case – a case with the combined function of a smart cover and a back protection case. This case is compatible with the iPad 2, and iPad 3rd & 4th generation devices.
- iTunes Store Account: Regardless of which operating system the iPad is synced, an iTunes Store account and Internet access are required to operate it.
- Controlling iPad: The iPad is designed to be controlled by bare fingers. Thus non-conductive gloves and styli do not work with its display. Special gloves and capacitive styli have been designed though to control the screen if needed.
- iBooks and iBookstore: All iPad have an optional iBooks application that can be downloaded from the App Store. The iBooks app displays books and other ePub-format content downloaded from the iBookstore. Major book publishers including Penguin Books, HarperCollins, Simon & Schuster and Macmillan have committed to publishing books for the iPad.
- Amazon Kindle, Barnes & Noble Nook and iPad: Despite its being a competitor to both the Amazon Kindle and Barnes & Noble Nook, both Amazon.com and Barnes & Noble have made Kindle and Nook apps available for the iPad.
- iSight Camera: With a 12‑megapixel (12MP) iSight camera, you can be sure to capture sharp, detailed stills like the ones shot on iPhone 6s. That includes shooting and editing 4K video, which is up to four times the resolution of 1080p HD video.
- Live Photos: Live Photos bring your still photos to life with sound and movement. Simply touch and hold anywhere on your 12-megapixel still and experience the moments just before and after it was taken, so your photos turn into living memories.
- FaceTime HD camera with Retina Flash: The Retina display isn’t just a place to see your content — it’s a flash for your FaceTime HD camera. Powered by a display chip that allows the display to flash three times brighter than usual, the Retina Flash helps illuminate selfies in low light and at night. And a True Tone flash matches the ambient light for more true-to-life colours and natural-looking skin tones.
- iPad and Space: Canadian astronaut Chris Hadfield took iPad with him to the International Space Station in 2013. He used the tablet computer for entertainment, listening songs and watching movies. How did the accelerometer work in space? Just nicely. A tip for future orbit walkers: shake your iPad to lock it in landscape mode.
