For more experienced Linux users, Knoppix makes a great way to try out different configurations. If something goes wrong, a simple reboot will bring it all back to normal.
From a simple system on-the-go, to a full-fledged OS, to a recovery system, to a quick test drive, its all only a boot away with Knoppix.
