I have been beta testing an application called PokerManager. I'm sure some of you have seen it. It is very much like PokerTracker. It does some things much better than PokerTracker. There are of course some things PT does that PokerManager doesn't do yet but the developer is very responsive and quick to implement good suggestions.
I am particularly interested in the built-in graphing capabilities. Check it out, come back here and let us know what you think. Nothing like competition to make the products better.
