While we're on the topic of installing Ubuntu which is agreed to be the easiest, may I recommend Ubuntu Ultimate http://ultimateedition.info/Ubuntu_Ultimate_1.6/ http://ultimateedition.info/Ubuntu_Ultimate_1.6/ Its just normal ubuntu but with different default packages installed, which are actually really useful (go to the site and read about it), and all repositories enabled. Some people really don't like this because they say its annoying but most people really end up downloading all these packages anyway...might as well save the hassle. Not to mention it comes with an interesting default theme.
