Apple has postponed the international launch of its iPad tablet by one month, to the end of May.
In a statement, the company admitted that stronger demand in the US has forced 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," the statement read.
"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."
The company said it would open online pre-orders for iPad outside the US on Monday 10 May, when it will also announce the device’s international pricing.
