Merging the iPad with Apple's notebook shipment numbers would make it the third-largest portable computer maker in the world, DisplaySearch said in a new study. Adding the 4.2 million tablets would give Apple 6.3 million shipments, it said, pushing it above Dell (6.1 million) and Toshiba (4.3 million). The result was actually low as it was based on preliminary figures; Apple's official results saw it ship over 2.6 million MacBooks and nearly 4.2 million iPads, or 6.8 million portables in total.
