Yup! Ubuntu is the most user friendly and the easiest to use, so is Gentoo but a little more advanced. Try dual-booting so this way if you dont like linux and its experience and controls, you can always go back to whatever you were using. Also try looking at the BackTrack linux distro. You might be surprised as to what you find, but DONT use the BETA!! ive used it and its extremely unstable, so if you happen to want to use it, then wait till it gets a patch, its updated, or a stable version comes out. Happy learning!
