hiho,
Do you know KNOPPIX? It is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk KNOPPIX is a debian based system, so it works with dpkg and apt.
KNOPPIX is really one of the best ways to show everyone how powerfull and also wonderfull linux is... you when you enjoy the distri you also can install it..... just try it...
