It’s easy to see why Ubuntu is the chosen one (pun intended) – one only has to pop in a CD on any fairly modern PC and see the results. A graphical desktop is available for use fairly soon and anyone who wishes to take the next step and install the distribution has a very easy setup to follow. Of course, there are plenty of other distributions which are equally usable – Ubuntu just happens to be the one which is best-known.

Source: Ubuntu? Not for me, thanks
