Virginia Tech’s “X” supercomputer, built with 1,100 Power Mac G5s, isn’t the only large collection of Mac used at the university — its new math facility houses more than 550 flat-panel iMacs. “In what used to be a five-and-dime store, a 60,000-square foot space has been converted into Virginia Tech’s Math Emporium, a state-of-the-art computer lab that serves 7000 math students each school year. Outfitted with nearly 550 iMac systems running Mac OS X, the Math Emporium has created a unique academic community in which students have control of their own learning.”
