There are no hard figures available to chart the Mac’s rise in scientific communities, but “anecdotal evidence suggests various Apple machines, from the Xserve G5 to the PowerBook, have become viable options,” according to E-Commerce Times. One example given is Virginia Tech and its supercomputing cluster built first with Power Mac G5s, then Xserve G5s. The university’s choice of Apple products was due to the computers’ “attractive price-performance ratio,” Virginia Tech spokesperson Lynn Nystrom told the E-Commerce Times.
