I am using Linux kernel based GNU OS since 2001. My first Linux install was PCQ linux. It was really nice distribution based on RedHat Linux. Since then I was a great admirer of RedHat distribution. With Fedora much has been changed in the original content. The most important utilities require specialist approach to work with. For example to make media player to play mp3 music we need external plug-ins to be installed. Software install is next big hurdle in making Linux a end-user friendly GNU OS.
    Ubuntu is definitely a winner when it comes to ease of user interactions. In other words it is Windows like OS. Installation is much simplified. Supports all media types like mp3,real media etc. Open office is much better than its previous versions. Open office word processor opens MS word documents as native document format. This was a major hurdle because MS .doc  is  dominant format.
