PW, SpectraLinux is made by a company I'm very familiar with
.
I like it because it's based on RedHat (the distro I'm most familiar with, and like the best) but it also includes updated versions of a large part of the programs. So when I install SL, I don't have to download 500megs of stuff as the first thing (that's what I usually do with RH, I run the up2date program to get the latest and safest versions of the programs).
There's also the additional CDs, one with third party programs and another with office.
A list of those third party programs and partners can be found here:

We've got people here that have made Finnish distros earlier, so it was an easy step to make a new distro for our purposes (development and servers...)
Enough of the advertisement....
