Charles Cooper writes, "When Sun Microsystems got started in 1982, companies such as Wang and Data General dominated the hardware business. In less than a decade, this upstart Unix outfit was a billion-dollar-plus phenom while the once-mighty minicomputer makers had been consigned to irrelevance. How times have changed nearly two decades later, with Sun now the one scrambling to remain relevant. As the Unix server market continues to shrink, sales of Intel-based servers running the Linux operating system nearly doubled in the fourth quarter of 2002 from a year earlier."
