Re: Fedora
This is a 1,000,000 $ question.
Basically, if you want set up a server box go for some Red Hat Enterprise Linux clone (CentOS, White Box) or Debian Stable.
If you need a workstation or notebook installation, my personal suggestion is:
1. Fedora Core - Pros: Red Hat compatibility, frequent updates; Cons: large installation, bloody RPM packaging system
2. Aurox - Pros: Red Hat compatible, focused on multimedia desktop; Cons: sometimes it takes a time to get the answer on a question
3. Debian - Pros: Stability (even "Unstable" edition is very stable), good support, very clean installtion, good packaging system; Cons: you have to go for Unstable edition to be up to date
4. Slackware - Pros: good packaging system, clean installation, clean configuration; Cons: It's one man show (whole distro is under control of 1 guy), support
Of cause you can buy some decent commercial distro like Novell SuSE or Mandrake, but you have to pay. On the other hand you'll get printed manuals (especially SuSE is very good) and full support. It's worth to try it.
