Apple could ship more than 10 million iPads a quarter for the first time in the spring, part suppliers claimed late Thursday. The company is still on track to ship 6.5 million iPads before April, two to three million of which would be the iPad 2, but would nearly double that in the spring to 10-12 million iPad 2s. Shipments would step up further to where Digitimes' insiders estimated 21.5 million to 24 million would ship in the last half of 2011.
