While choosing a Linux distro, the first thing you need to ask is why do you want to use it? or what is its use? The professional or commercial use of LINUX distro will require different distros. For example, if you are planning to use it for tracking you finances or you are interested to serve a marketplace then same types of bistros should not be used. That will be quite a bad choice. Though you can be a new computer user but still you can probably decide it is quite a foolish act.
