Apple has sent word the company has sold more than two million iPads in less than 60 days. The device finally went on sale last Friday in nine additional countries including the UK, after "unprecedented US demand" had delayed the international launch. Earlier this month, Apple said it had sold a million iPads in the first 28 days. Supplies of the gadget have fallen short of demand, and Apple has imposed restrictions on the number a person can purchase.

"Customers around the world are experiencing the magic of iPad, and seem to be loving it as much as we do," said Steve Jobs, Apple's CEO. "We appreciate their patience, and are working hard to build enough iPads for everyone."

Queues formed over night at many iPad stockists last week, including Apple Stores, Apple Premium Resellers and branches of PC World, Currys and Dixons.

The iPad will go on sale in nine more countries -- Austria, Belgium, Hong Kong, Ireland, Luxembourg, Mexico, Netherlands, New Zealand and Singapore - in July, and additional countries later this year, Apple said.

The iPad is driving the burgeoning popularity of tablets, shipments of which could grow sixfold by 2014, IDC said in research released on May 20. Tablet shipments could total seven million by the end of this year, and top 46 million by 2010, IDC said.

The iPad is a handheld device with which users can view movies, surf the Internet, read e-books and play games. It has no physical keyboard, but one can be displayed on its 9.7-inch touchscreen display. It is 1.27cm  thick and weighs 680g.
