The company has sent out the following press release blaming unprecedented demand for the delay.
"Although we have delivered more than 500,000 iPads during its first week, demand is far higher than we predicted and will likely continue to exceed our supply over the next several weeks as more people see and touch an iPad. We have also taken a large number of pre-orders for iPad 3G models for delivery by the end of April."
"Faced with this surprisingly strong US demand, we have made the difficult decision to postpone the international launch of iPad by one month, until the end of May. We will announce international pricing and begin taking online pre-orders on Monday, 10 May. We know that many international customers waiting to buy an iPad will be disappointed by this news, but we hope they will be pleased to learn the reason - the iPad is a runaway success in the US thus far."
Asked last week if the huge popularity of the iPad in the US would delay the international launch, Apple's CEO Steve Jobs said no, claiming the end of April was still the release date outside the US for the iPad. Apple has updated the UK online website to reflect the delay. 'Coming late May,' Apple now say.
