One thing I noticed is that (and I assume this has something to do with having FreeCell cooked into ROM instead of being installed afterward) the statistics aren't exactly accurate. If you are in the middle of a game and close FreeCell, it's like that game never existed... when in fact it should show up as a loss. The only way a loss shows up is if you actually lose a game (no more available moves) or if you start a new game before you finish the current one.
Odd little quirk... no big deal, but it's there. Taking advantage of this quirk, however... I'm 28 and 0 since I upgraded to WM6
