From what I understand there are various Linux mirrors out there for the taking. The question I have is what is the main difference? What i mean is, is XP more secure? I don't have any experience with Linux, but was considering trying it as a main OS. I know there's probably a lot of differences, but do these mirrors offer free updates to security issues like microsoft, and how hard is it to find compatable antivirus/spyware programs that truly work with it? Also can anyone comment on the difference in gaming issues?
