And anothere success story for accurate reporting.  How much memory is "2
gigahertz"?

"Michigan State University graduate student Michael Shafer stands next to the
computer in East Lansing, Mich., Wednesday, Dec. 3, 2003 he used to discover
the worlds highest prime number. Shafer ran a Dell Dimension PC with 2
gigahertz of memory and an Intel Pentium 4 microprocessor _ 'like you'd get at
Circuit City' _ in his office for 19 days until Nov. 17, when he glanced at the
screen at 2:30 p.m. and saw 'New Mersenne prime found.' The number is 6,320,430
digits long and would need 1,400 to 1,500 pages to write out. (AP
