Apple is the creator of all iPhone and iPad tablets, everyone was creating a fuss with the Tablet that it is the best of them all but the Xoom was officially voted the best Tabletof the Mobile World Congress. The Apple Stores of America (not all) have run out of stock, the scheduled stock arrival is Tuesday according to of the the stores.
Due to all this havoc, Apple has also declined orders even though the consumers only ordered 1 iPad. Maybe the staff is slow in manufacturing them. When the Nokia N8 was launched, no orders were declined and the stores did run out of stock but they were quickly scheduled for another batch of N8 devices to arrive.
