There are hundreds of Linux distributions out there. A person can spend a lot of time going through them all. However, some distributions are much better than others. Today, Ubuntu seems to be the most popular distribution of Linux because it is easy to use. Linux was not ready for the masses until something easier came along. Ubuntu Linux was released in 2004 and since this time a lot more people switched to Linux. Ubuntu has a lot of financing behind it comparing to other distributions. The best thing is that it is completely free and has a large amount of free software that you can install. Majority of people who currently use Windows will not have a big problem changing to the Ubuntu Linux operating system.
