Apple said it has sold more than 300,000 iPads on Saturday, the day it debuted across the United States.
Sales included pre-orders of the iPad, a new type of touch-screen device that blends features of the iPhone, electronic book readers and tablet computers.
The basic model of iPads that connect to the Internet through Wi-Fi was priced at $499. Apple will sell costlier iPads with cellular data connections later this month.
Apple said that iPad owners downloaded over a million applications from its app store and more than 250,000 electronic books on Saturday.
