Linuxguide: "The easiest way to begin using a Linux system may be to use an already running system. For example, some systems may be available in various educational or work environments. In this case you only need to contact the appropriate administrator and obtain a user ID and password. You will only be able to explore the system to a certain extent, but the first steps can be taken without having go through the installation process. Another trouble-free way of obtaining a Linux system is to buy a computer with Linux pre-installed. The number of vendors selling such systems is constantly increasing."
