![]() ![]() The first two iPads used a 1024 by 768 pixel display, while the third generation model quadrupled the number of pixels to 2048 by 1536. The iPad's standout feature is its screen, and that's especially true with the third and fourth gen models. The iPad Smart Cover is purchased separately from the tablet itself. The cover helps protect the screen while conserving battery life. And once the cover is on the iPad 2, the device switches to sleep mode. The cover can be opened and folded into a triangular shape to prop up the iPad 2 and serve as a stand. The iPad Smart Cover uses magnets to latch on to the iPad and cover it snugly. With the launch of the iPad 2, Apple introduced a new type of cover for the device. The base model comes with 16 gigabytes of flash storage, but for $100 or $200 more you can upgrade to 32GB or 64GB, respectively. Of course, every iPad includes a WiFi chip, and Apple sells models with 3G and LTE cellular support. Other key components of the fourth generation iPad include 1GB of RAM, a 720p FaceTime front-facing cam, 5 megapixel rear camera, a 42.5 watt-hour battery, Bluetooth 4.0, standard sensor package (gyroscope, accelerometer and ambient light sensor) and a digital compass. For instance, the iPad can be viewed clearly from a viewing angle of 178 degrees. The viewing angles and colors of IPS displays are superior to standard or twisted nematic TFT screens typically found in notebooks and flat-panel monitors. The iPad uses an IPS, or in-plane switching, LCD planel. The closer-to-square design keeps the iPad from being awkwardly tall or wide in either portrait or landscape orientation, though the trade-off is that widescreen videos can't make as much use of the screen space. Unlike most Android tablets, Apple has chosen a 4:3 aspect ratio for the iPad instead of the widescreen 16:9. The fouth generation iPad measures 9.5 inches (24.1 centimeters) tall by 7.3 inches (18.5 centimeters) wide and 0.4 inches (1 centimeter) deep. The iPad's only other buttons sit on the right side of the device: a rocker controls volume, while another button can serve as mute or rotation lock for the screen. A power button sits at the top edge of that curved surface. ![]() The iPad's build looks more like an iPhone 3GS than the newer iPhone 4 or iPhone 5, thanks to a smooth, curved metal body. The front also houses a webcam for Apple's FaceTime video chatting, while the back has a higher resolution camera for taking better photos. Apple offers two different iPad colors: one with a black face bezel and one with a white face bezel. The front is dominated by a 9.7-inch (24.6-centimeter) touch screen, with a single button (the same Home button found on the iPhone) placed below it. Like the iPhone, the iPad is primarily a touch device. To understand why the iPad is such a successful and popular device, we've got to look at its features, including an intuitive user interface and a store containing thousands of downloadable apps. Hardware is only part of the equation, however. And since the release of its original model, Apple has modified and improved the iPad with faster internals and a higher resolution screen to keep it ahead of the competition. At $500 or more apiece, it's safe to say the iPad has been a tremendous success. Or, rather, Apple created the tablet business: With the launch of the iPad, Apple created a market for touch-based devices designed for watching videos and browsing the web and reading digital books and e-mail.īetween the debut of the iPad in early 2010 and the release of the fourth iPad revision in late 2012, Apple sold more than 100 million tablets. And just as the company had changed the smartphone business with the release of the iPhone, Apple changed the tablet business. Some critics complained that the iPad was just a big iPod Touch. Its sleek finish and unique engineering scream Apple design. It's much larger than those two related devices, yet smaller than a notebook computer. In fact, people had been talking about an Apple tablet for years - people even guessed the name of the device correctly in advance.Īt first glance, the iPad looks like an iPhone or iPod touch on steroids. That didn't stop journalists, bloggers, reporters and analysts from talking about the device. As is common with Apple products, the iPad's development was kept behind a curtain of secrecy. That was the day the company announced the release of its much-anticipated iPad. ![]()
