I am going to be getingt a new laptop soon. I have been using Windows till now but have had some experience with Linux too. Now I want to completely shift towards Linux and for that purpose I was Googling to find out which distro of Linux to go with. I found Fuduntu, BackTrack, CentOS and Fedora interesting. In Fuduntu, they say, it is 30% more efficient on battery. I have used BackTrack, and I found that it provides hell lot of tools for hacking and other tasks.
I am confused as to which OS should I install. I am looking for guidance as to where I should look to learn more about the different distributions of Linux that are out there. Where should I be looking?
