SAN FRANCISCO: Apple said Monday it sold three million iPads in the first three days of its launch of the iPad mini and fourth-generation model of its original format iPad.

The tech giant said demand for iPad mini “exceeded the initial supply,” meaning some orders will be delayed until later this month.

Apple did not break down precise sales of the mini, the 7.9-inch (20 centimeter) tablet which joins several other small-format tablets, and the new iPad, which has a 10-inch (25 centimeter) screen.

“Customers around the world love the new iPad mini and fourth-generation iPad,” said Tim Cook, Apple's chief executive, in a statement.

“We set a new launch weekend record and practically sold out of iPad minis.

We're working hard to build more quickly to meet the incredible demand.”Both iPad mini and the new fourth generation iPad were launched Friday in 34 countries.

The iPad mini weighs 0.68 pounds, 53 per cent lighter than Apple's third generation iPad. It is 7.2 millimeters (0.28 inches) thick, 23 per cent thinner than the original iPad and thinner than a pencil.

The iPad mini with Wi-Fi connectivity and 16 gigabytes of memory costs $329, the 32GB model sells for $429 and the 64GB version for $529. It is more expensive than rivals from Google, Amazon and other makers.

Apple's senior vice president for marketing Phil Schiller helped unveil the iPad mini, insisting that it was an entirely new design and not “just a shrunken down iPad”.

Like later versions of the original iPad, the new Apple tablet features rear- and front-facing cameras, and also has stereo speakers.
