The Linux operating system is literally taking the world by storm. Promising lower costs, higher performance, and better stability and security than its Windows counterpart - not to mention freedom from being locked into a single supplier - Linux is on a roll. As an operating system for servers, Linux has seen double-digit growth rates for seven consecutive quarters. Fully embraced by the likes of IBM, Hewlett-Packard and Sun, the ubiquitous Linux-based server has already established itself as the low-cost, high-reliability alternative to the traditional Windows-based server. Linux on the desktop, however, is a slightly different matter.
