I've only read (mostly) about windows and linux, and how much one sucks and the other rules, on any posts having to do with them. I've read a bit about FreeBSD, but not that much.

What I would like to know is about the other OSs out there besides windows. I would like to know what makes one good and another suck, what each is best for, Why are many based on Unix, what the advantages and disadvantages of them are, etc. I'll take all the info I can get.

Thank, much appreciated.
