Checking out the iPhone's applications
Congratulations. You've selected one of the most incredible handheld devices we've ever seen. Of course, the iPhone is one heck of a wireless telephone, but it's actually four awesome handheld devices in one. In addition to being a killer cell phone, it's a gorgeous widescreen video iPod, a decent 2-megapixel digital camera (original iPhone and iPhone 3G) or 3-megapixel camera/camcorder (iPhone 3GS), as well as the smallest, most powerful Internet communications device yet.
In this chapter, we offer a gentle introduction to all four devices that make up your iPhone, plus overviews of its revolutionary hardware and software features.
The iPhone has many best-of-class features, but perhaps its most unusual feature is the lack of a physical keyboard or stylus. Instead, it has a 3½-inch super-high-resolution touchscreen (160 pixels per inch if you care about such things) that you operate using a pointing device you're already intimately familiar with: your finger.
And what a display it is. We venture that you've never seen a more beautiful screen on a handheld device in your life.
