At first glance, the iPad looks like an iPhone or iPod touch on steroids. It's much larger than those two related devices, yet smaller than a notebook computer. Its sleek finish and unique engineering scream Apple design. But many are wondering: What exactly is the iPad? The quick answer is, it's a digital media tablet. If you're even more confused now, don't worry. This article aims to shed some light on the device that has sparked so much buzz.
iPad Design
Even the naming of Apple's newest device has been a topic for debate. While iPad suggests a notepad, it's more commonly referred to as a tablet. The iPad is more than just a giant iPod Touch. It's a hand-held multimedia device that incorporates much of what you'd find in the iPhone and iPod touch. Its physical resemblance lies somewhere between the iPhone and the aluminum-shelled Macbook line. At 9.7 inches (24.6 centimeters), iPad's screen also lies somewhere between the iPhone and Macbook in both size and technical specifications. Let's look at the display first in this comparison chart below:iPad | iPhone | iPod Touch | Macbook Pro | |
Display Size | 9.7 inches (24.6 centimeters) | 3.5 inches (8.9 centimeters) | 3.5 inches (8.9 centimeters) | 13.3, 15.4, 17 inches (33.8, 39.1, 43.2 centimeters) |
Orientation | 4:3 aspect ratio | Widescreen diagonal | Widescreen diagonal | 16:10 aspect ratio |
Interface | Multi-touch w/IPS | Multi-touch | Multi-touch | None |
Resolution | 1,024 x 768 pixels at 132 ppi | 480 x 320 pixels at 163 ppi | 480 x 320 pixels at 163 ppi | 1,920 x 1,200 pixels |
Sensors | Ambient light | Ambient light, proximity | None | None |
Material | Fingerprint-resistant oleophobic coated glass | Fingerprint-resistant oleophobic coated glass | Fingerprint-resistant oleophobic coated glass | Mercury, arsenic-free glass |
LED-backlit | Yes | No | No | Yes |
The iPad integrates IPS or in-plane switching technology. IPS displays are superior to standard or twisted nematic TFT screens typically found in notebooks and flat-panel monitors. An IPS display has increased clarity and color reproduction and can produce greater viewing angles. For instance, the iPad can be viewed clearly from a viewing angle of 178 degrees [source: Brandrick]. IPS technology stems from the way light travels through the crystals that make up the LCD. If you've ever worn a pair of polarized sunglasses, you may have viewed computer screens or LCD displays only to see images on them disappear as you change the angle at which you're viewing the screen. This is a similar effect to what happens when the viewing angle of a twisted nematic TFT increases. The iPad's IPS display guarantees optimum viewing enjoyment at almost a 180-degree angle. ISP also supports 8-bit color processing versus the standard 6-bit found in twisted nematic displays.

So far, we've discussed the iPad's design. Now let's talk about what it does. If you're familiar with the iPhone or iPod Touch, chances are you could pick up an iPad and start using it without much trouble.
All three devices change picture orientation by simply rotating the device via built-in, three-axis accelerometers, but the iPad has something its smaller cousins lack: the screen rotation lock. This allows the iPad's screen orientation to be locked in either portrait (vertical) or landscape (horizontal) orientation.
Like the iPhone and iPod touch, iPad has a full QWERTY on-screen keyboard. When the devices operates in landscape mode, the iPad's virtual keyboard is almost the same size as keyboards found in iMac systems.

According to Apple, the iPad runs most of the more than 150,000 applications currently available for the iPhone and iPod touch. The iPad comes loaded with 12 next-generation multi-touch applications, including the Safari browser and redesigned Mail application. Also included are iPod and iTunes apps as well as YouTube, Maps, App Store, Notes, Calendar, Contacts and iBooks.
As with any Apple product, you can expect a diverse range of accessories for the iPad. One is the iPad Keyboard Dock, which connects with the iPad in the vertical orientation. The keyboard docking system allows you to use a full-size keyboard and turns the iPad into more of a computer display. But it's important to point out that the iPad isn't a computer. We'll get into that more later in the article.
OK, you're getting closer to fully understanding the iPad. How about we look at some technical data now? Let's break down each model in the next section with a comprehensive comparison chart. You'll find there isn't really a whole lot different between the six models - except, of course, price
iPad Technical Information
You can buy an iPad in one of three storage configurations, either with Wi-Fi only or Wi-Fi plus 3G. Perhaps the best way to visually represent what you get with each model is with a simple comparison of features:Wi-Fi Only | Wi-Fi plus 3G | |
Width | 7.47 inches (19 centimeters) | 7.47 inches (19 centimeters) |
Depth | 0.5 inches (1.3 centimeters) | 0.5 inches (1.3 centimeters) |
Weight | 1.5 pounds (0.7 kilograms) | 1.6 pounds (0.7 kilograms) |
Storage Capacity | 16 GB, 32 GB, 64 GB | 16 GB, 32 GB, 64 GB |
Storage Type | Solid state | Solid state |
Price | $499, $599, $699 | $629, $729, $829 |
Processor | 1GHz Apple A4 | 1GHz Apple A4 |
Battery Life | 10 hours | 10 hours |
Battery Lifespan | 1,000+ charges | 1,000+ charges |
Pre-loaded Apps | 12 | 12 |
Case | Recycled aluminum | Recycled aluminum |
Wi-Fi | 802.11a/b/g/n | 802.11a/b/g/n |
Bluetooth | 2.1 + EDR technology | 2.1 + EDR technology |
3G | None | UMTS/HSDPA (850, 1900, 2100 MHz) GSM/EDGE (850, 900, 1800, 1900 MHz) Data only |
AT&T Data Price Plan | None | $14.99/month (250MB), $29.99 (unlimited) |
Video | Up to 720p, 30 frames per second | Up to 720p, 30 frames per second |
Micro SIM Card Tray | None | One |
As you can see, there's not a whole lot of difference between the two models. But a few things do set them apart, most notably 3G capability.
The Wi-Fi models work much the same way a notebook or netbook computer works. All three devices communicate with a wireless Internet connection via built-in Wi-Fi. You would be subject to the same Wi-Fi hotspot limitations with this iPad model as you would a notebook computer. The Wi-Fi + 3G model allows you more freedom to browse the Internet and check e-mail. By utilizing similar wireless and cellular technology found in the iPhone, you can tap into the Internet using 3G service, but it'll cost you. If you go this route, not only will you pay an additional $130 for the 3G-enabled device, you'll need to purchase one of two 3G data plans through AT&T. Plan on an additional $15 or $30 per month, depending on how much data you want. Regardless of which plan you choose, as of this writing, you don't have to lock into a contract. If you choose to, you can purchase 3G data sporadically, depending on how much you intend to use. If you do choose the Wi-Fi + 3G model, don't expect to be walking around holding the device up to your ear and calling your friends. Like with the iPhone and iPod Touch, you'll be able to access all your social networking sites and use e-mail on the run, but the iPad isn't a phone. When you pay for 3G service, it's for data only.
If you're new to Apple products, you may not be familiar with CEO Steve Jobs. The Apple founder is a mercurial individual and has a unique way of doing things. He's known for his showmanship at company media events, and when he unveiled iPad at a keynote seminar in March 2010, plenty of people were hanging on his every word. In the next section we'll look at what some in the media have said and delve into some of the shortcomings that may keep iPhone or notebook owners from dropping all that coin on a new gadget.
Critical Response to the iPad

Like every other portable device in Apple's line, you can't replace the iPad's battery. Should you get to the end of the iPad battery's lifespan, which Apple estimates is around five years, you would send your device to Apple for a replacement at a cost of $99. That may not be so bad, considering batteries are usually expensive for portable devices and five years is much longer than you'd get out of many batteries in other devices.

Perhaps the one thing that may keep iPad from bridging the gap between smartphone and notebook is Apple's unwillingness to incorporate Adobe Flash in the gadget. Like the iPhone and iPod Touch, the iPad doesn't support Flash, meaning you won't be able to view many videos on the Internet. Apple CEO Steve Jobs contends Flash is quirky and leads to unnecessary software crashes. He has said that if the iPad used Flash, the device would operate for 1.5 hours per charge rather than 10 [source: Elmer-DeWitt]. Critics dispute these claims, and point out that Flash users would be able to circumvent iTunes for content typically only available through Apple's online media store. Apple may eventually permit Flash on the iPad, iPhone and iPod Touch. But for now, iPad follows the precedent set forth by its brethren and doesn't support Flash.
Now that you fully understand iPad and all it can do, in the next section we'll take a look at what it means to the burgeoning digital media market currently dominated by Amazon.
iPad as a Digital Reader
E-book War As of this writing, Apple and independent book publisher Perseus Books had recently signed a deal for the publisher to resell its books on the iPad through Apple's iBookstore. Amazon with its Kindle has roughly 90 percent of the digital media market, but some expect the deal between Apple and Perseus to change the way electronic books are sold. Amazon controls pricing of books sold through its Kindle Store while the deal between Apple and Perseus and books sold through iBookstore would be on par with how Apple deals with third-party developers through its App Store. Retailers would set the price of their products and Apple would receive 30 percent of iBookstore sales [source: Macworld]. |
Amazon's Kindle is an extremely popular e-reader. But, for the moment, it's dedicated solely to reading electronic books. Apple's iPad can do much more. With Apple's iBookstore, iPad will be an e-reader ready to rival Kindle. But Amazon has a Kindle app already available in the App Store, making it possible for you to buy books from its store and read them on the iPad.
Another digital device iPad is sure to lock horns with in the virtual media market is Dell's Mini 5 prototype, a digital media tablet much like iPad. Set to debut sometime in 2011, the Mini 5 is smaller in size; analysts believe the feature-rich device will run some version of Google's Android operating system. As it stands, many feel that the e-book segment is on the verge of exploding. Newspapers have been cutting staff to save costs and focusing more on online content. The e-reader could end up saving the newspaper industry. That, like iPad's success, will only be known over time
