Stability

Linux has long been praised for its stability--Linux boxes are known for running months or even years at a time without crashing, freezing, or having to be rebooted. Linux users sometimes poke fun at other, less stable operating systems, by way of screensavers like BSOD (Blue Screen of Death, which displays crash screens from various other platforms).

Linux is extremely secure compared to other platforms. Viruses and Trojan Horse programs are practically non-existent. Linux servers practically run the World Wide Web, so one cannot argue that there are so few malicious programs for Linux because it represents an insignificant number of target machines.
