Let me give you a handle on how big (physically) this farm is: half a million square feet, with another half million they're planning on building.<p>In comparison, the Boeing Everett plant, where they manufacture half the world's airliners, is 4.2 million square feet. That building contains, IIRC, four production lines.<p>The Apple server farm, when finished, will be the size of the Boeing 747 assembly line.
