I absolutely love this FW, always have and it's the one I always go back to. The only thing that bothers me is it still safe to use it? I'm on a XP machine that is well hardened, running minimal services but not behind a router. My rules are tight and I also run Avira and Threatfire. I've read some older threads on the subject, however i'd like opinion whether this great FW is still relevant today, in the here and now. I almost forgot to add, I have no concern for leatests/advanced outbound.
