I have been using BackTrack since the first version if I remember right and now there has been version 5.0 out for a few weeks and I have to say that it works like a dream and works on my hack laptop much much quicker than older version.
So if you are in the security/pentest business or just like to learn things (Of course this work for blackhats too…) you should try this because backtrack is completely free.
You can download it here BackTrack.
