     The iPad is an Apple tablet computer. The device sits somewhere between a laptop and a

smart phone, according to Apple's chief executive, Steven P. Jobs, and does certain things better

than both of them, like surfing the Web, reading e-books and playing videos. The iPad went on

sale on April 3, 2010, and Apple said it had shipped 500,000 units in the first week. The handheld

device puts Apple on a direct collision course with the Kindle from Amazon, which Mr. Jobs ever

considered as pioneering the category.

     It is common knowledge that media companies hope the iPad will finally lead to available way

for them to charge for news, books and other materials. The half-inch thick, 1.5-pound device

features a 9.7-inch multi-touch screen and is powered by a customized(订制的)Apple microchip,

which is called A4. It has been designed with an exposed screen and without a camera or separate

keyboard. The iPad has the same operating system as the iPhone and also has access to its 140,000

applications.

     The price of the device starts at $499 for the most basic model, with a Wi-Fi wireless connection.

More expensive models with more memory and with 3G wireless access will cost $629 to $829,

depending on storage size.

     Because Apple is attempting to popularize a new kind of computing device, acceptance among

consumers is expected to be slower than with previous Apple devices. Critics assume that some

buyers are waiting for future versions of the iPad to appear, perhaps with a camera or USB ports

(端口).

     On its first day on sale, iPad users downloaded more than one million applications from the

company's AppStore and more than 250,000 electronic books from its iBookstore. A new wave

of apps is expected in response to the iPad. For an application developer, having an application

accepted for a highly desired Apple product means reaching a passionate group of consumers.

The potential income is huge: the apps market for the iPhone and iPod Touch alone is already

worth a billion dollars a year in sales.
