Ok, thanks to those who voted. It seems Mandrake won!

I haven't tried Mandrake yet but your kind votes are pushing me to trying it. I will try Mandrake when I backup my data and reformat the harddrive to install the new OS.

Thanks again to those who voted!

I really like SuSe Linux. We use that at work and I just love working with it.

I like both SuSe and Mandrake (both pretty too) but Red Hat still has my vote. You can't beat the "universal" support out there and good hardware support too.
/shrug

yeah, Red Hat is really nice too. The good ol' standard

Can you add Ubuntu up there?

done...

I am really liking Ubuntu right now... (I also like Fedora/Redhat, and Mandriva/Mandrake)

Ubuntu & Knoppix are my favorites, but I've also had used Red Hat, DSL, and OpenSuSE.
