Apple announced that it has sold a million iPads since the tablet computer was launched on April 3 this year.

"One million iPads in 28 days - that's less than half of the 74 days it took for the iPhone to achieve this milestone," Apple's CEO Steve Jobs said, adding that the millionth iPad was sold on April 30.

iPad users have already downloaded over 12 million Apps from the App Store and over 15 million ebooks from its new iBookstore.

"Demand continues to exceed supply, and we are working hard to put this magical product into the hands of even more customers," Mr. Jobs said.

The 0.5-inch tablet computer, which weighs 1.5 pounds, enables users to browse the web, read and send email, watch HD videos, listen to music and read ebooks through its multi-touch user interface.
