Apple today announced that it will delay the planned international launch of its iPad tablet computer. The Cupertino, Calif.-based company says it will announce international pricing and begin taking online pre-orders on Monday, May 10.

According to its statement, Apple has already delivered more than 500,000 iPads during the first week.

Apple said that demand in the United States far exceeded the company’s expectations, adding that additional orders will likely continue to exceed supply over the next several weeks. The company also says it has taken a large number of pre-orders for iPad 3G models for delivery by the end of April.

Apple had announced previously that it sold over 300,000 iPads in the first 24 hours following the iPad launch. Those sales included deliveries of pre-ordered iPads to customers, deliveries to channel partners and sales at Apple retail stores.
