I haven't tried Xandros, but I like Suse Yast, easier configuration GUI I had used. I had installed about 10 or so Red Hat Enterprise (v4) and the setup is easy, but after setting it up the software instalation doesn't work (I had called Red Hat to complain about it, and they did not wanted to recognize it)
I have to use Red Hat for work (boss wanted it)
I have Suse in a Vmware on my laptop as well as Ubuntu. I like the package software for Ubuntu though )and the clean interface. And I love the size of dsl. There is a linux distro for each need.
I will stay in XP for a while because .....I play lots of games. But at work I was using more and more Linux (syslog servers, monitoring server, and I was about to install a snort too)
It is starting to gain ground on me. Today I finished studying for Linux +, and now I will start LPCI Junior Level.
