A "virtual machine" can be used to evaluate new operating systems before trying an full install to hard drive. Also useful for trying out different desktop and window managers (GNOME, KDE, LXDE, Unity, Cinnamon, Mate, OpenBox etc), bleeding edge updates, or experimental software, without adding bloat to your day-to-day OS, or the risk of making it unstable.
