Jon L. Jacobi

Born in southern California to a Marine Corps family, Jon had traveled through much of the U.S. by the time he was eight years-old. A twenty year residence in Stamford, CT with four years commuting to Juilliard in NYC, was followed by a move to San Francisco, where he still resides. His involvement with computers started with a family friend's punch card entry job, an IMSAI 8080, then every personal computer made by Atari, Commodore, Apple, and IBM. Since joining PCWorld's (then PC World) freelance writing team in 1995, his writings have been published too many times to count in that worthy journal, as well as CNET, Computer Currents, Forbes, Wired, and many others.
