I use samba and an Rsync script i made to do incremental backups of my my documents (shared by samba) to my linux server

cause that's what i like about whs. It'll automaticaly back up files and settings and you can restore them if your computer crashes.

I havent tried it. I dont think its out over here

I tried the beta, which was a little buggy, but nonetheless I liked it. I would recommend it, expect it only works on xp and vista, obviously.

2k?

no. I guess MS wants to completley get rid of 2000 and below, I think they probably won't support xp for much longer.
