Oh one more thing. If your intentions are to learn linux/gnu then get away from GUI based OS's like Ubuntu, Suse, Mandriva. etc. Drop yourself into a CLI environment and fight your way out, lol. A couple of weeks with Slackware, Gentoo, or LFS (if you're brave and REALLY wanting to learn) will increase your CLI skills quickly. You can use those GUI based OS's for years and never learn anything. Really!
