Apple in a milestone is moving into HP's old headquarters, the company confirmed late Wednesday. HP has signaled that it has sold its decades-old campus at 19091 Pruneridge Avenue in Cupertino, just five minutes' drive from Apple's 1 Infinite Loop, in favor of consolidating around Palo Alto. While it declined to name the buyer, Apple spokesman Steve Dowling confirmed that his company had bought the soon to be vacated space.
