I am weird I guess. I have 2 operating systems for my Sony Vaio. They reside on two seperate hard drives (with their own slide-out caddy for quick-swapping). Of course I have Windows XP on one drive with most of my files. Then the other, which you see here, and I am currently running, is Ubuntu. Ubuntu is a Debian-based Linux distribution that totally rocks. It’s free, and so are just about all of the programs that run on it.
