poker software

Was wondering if any of you guys use any poker software such as poker tracker, and if so how do you rate them?

I know a lot of our members use Poker Tracker and have found it very useful in helping to evaluate and improve their game. I myself haven't downloaded it yet, but I know I really should so I can look back and see the kinks in my game.

If you want to try it out, you can download Poker Tracker using this link.
