With Apple's new iPad, supply chain is the hero

Apple's new iPad will go on sale March 16 and sellouts are widely expected, but the real hero will be the company's supply chain. It's a juggernaut that can move 1 million units in a product launch without blinking.

Gene Munster, an analyst at Piper Jaffray, is already projecting that Apple will top 1 million new iPad units in a day. That first wave of product is hard to replicate by most vendors.
