Linux is my favourite operating system. I'm not at war with Microsoft, I just like Linux because it's nice, it works very well and, most of all, it's free.
I've used a couple of distributions: Red Hat and Gentoo. Gentoo is the one I liked most but I had to dismiss it as it took to me more time to keep it up to date than to use it.
