The iPad measures 9.56 by 7.47 by 0.50 inches (242.8 x 189.7 x 13.4mm). The 9.7-inch LED-backlit is a touch-screen that has a 1024-by-768-pixel resolution. As you can see from Figure 3, the screen is framed by a 1-inch black border. When you are holding the iPad vertically you can see the Home button on the bottom. This button will be familiar to iPhone and iPod touch users.

While the front of the iPad looks like a giant iPod touch, the back, as shown in Figure 4, is a classy brushed aluminum rather than the shiny back of the iPod touch.

The iPad comes in several models. There is a Wi-Fi only model that supports 802.11 a,b,g, and n. There is also a model that has 3G cellular support with service from AT&T as well as Wi-Fi. Currently prices range from USD 499 to USD 829. If you purchase a 3G version, you will have to pay AT&T for coverage. Currently they are offering service with no commitment or contract to sign so you can switch the service on and off as you like. You can also purchase continuous coverage at USD 14.99 per month for 250 MB or USD 29.99 a month for unlimited data. Unlike the iPhone, if you don’t get AT&T service for your 3G iPad, it will still work through the Wi-Fi connection.
