Hello, For anyone who has ever had an interest in Linux and who has about 600MB free on their computer, you might want to look at a small application called qemu. It will allow you to download the iso for Ubuntu onto your computer and use that ISO to run the live CD from Windows. That means, you can run Windows and Linux side by side similtainiously. If you want to demonstrate Linux on another PC, you could also copy the iso and the Qemu executable onto a pen drive and use it directly from that. Another solution I have worked on is installing Ubuntu onto a pen drive for use on any PC's that support booting from USB. This enables anyone to use any computer without installing any editional software. It also has accessibility enabled by default along with the latest version of Firefox and the Orca screen reader from SVN. Using it on a pen drive as aposed to a live CD means you can easily make changes to the running environment and save files as if you were using an installed version on your computer. On a CD, the environment is not persistent therefore all changes will be lost at shut down. Darragh
