FN: Why Ubuntu?
I love trying out new distros, and Ubuntu was simply too hot to pass up. Once I tried it, I found it to be pretty much to my liking, especially since it utilises the Gnome desktop, which is still my favourite (and the one I still find to be easiest for newbies to ease into). It is also Debian based, which, after my experience with Xandros, I have come to appreciate more than the alternatives (RPM for example).
