SEOUL, June 11 (Reuters) - Apple's iPad, initially viewed as a Web entertainment gadget for consumers, is quickly making inroads across businesses in Asia as wedding planners, luxury hotels and airlines hook up to the tablet computer.

Apple has sold over 2 million iPads since the device made its debut in April in the United States. It had to delay the international sale due to difficulty in meeting demand for the product, which has received high marks for videos and games, reading electronic books and general Web browsing.

''It's strong adoption in Asia means iPad could become another strong source of revenue for Apple and it would be not just Asia as myriads of applications that iPad has would make it possible for enterprises to offer personalized experience to their customers,'' said Lee Chae-gi, research director at Gartner in Seoul.

Apple now gets almost three-fifths of its revenue outside the US, and is counting on its base of fans who already own an iPod, iPhone or Mac to add the iPad to their collection as rivals line up with their own tablets.

In Japan, wedding service firm Novarese Inc is using iPads to help customers choose a wedding dress at its flagship store in Tokyo's Ginza shopping district, and plans to adopt iPads at seven other stores and its wedding ceremonial halls.

The firm now shows customers video clips of models strutting with dresses on the iPad, making it easier to see things such as how a hemline flares.

''We once considered showing it to customers on laptops but they are heavy. The iPad perfectly fits our demand,'' said company spokeswoman Kazuka Nohara. ''We also found something unexpected. Grooms are now more proactive in selecting a wedding dress.''

InterContinental Hotels is equipping concierges at centres including Hong Kong, London and New York with iPads to provide guests recommendations of restaurants, performances and local destination videos.

''Whether it ultimately becomes a useful tool in a corporate environment will depend on the ability of software developers to adapt business software to the new style of interface,'' said Tim Renowden, an analyst at technology consultancy Ovum.

In Australia, Jetstar, the budget carrier of Qantas Airways, became one of the first airlines in the world to announce it would offer iPad as part of in-flight entertainment.

It plans to rent an iPad out from A$10 ($8.30), enabling passengers to read e-books, play games and watch some pre-selected movies and television programmes on flights.
