Is Open BSD 3.3 good is good to use in everyday task or insted use linux redhat??

On the whole, OpenBSD probably doesn't make a great desktop, and there's more software available for Redhat. Of course, if you don't like having lots of GUI configuration tools, etc., you might like OpenBSD (or indeed FreeBSD or NetBSD).

I guess that all depends on what your everyday tasks are. I carry an old laptop runs OpenBSD to client sites to run network audits and security tests. I also use it during meetings to take notes. I find OpenBSD to be quite useful as a laptop; however, I would recommend Linux if you are just starting out. The learning curve for most of the major distributions is less steep than for OpenBSD.
