I just got ACE Tennis charting for my Tungeston Palm. Has anyone seen this? It took a little bit to get used to it, but it is very cool - and actually easy to use. It shows all kinds of % of what happens during a match - winners and errors, serve % and winnning % and even prints out diagrams showing winners and errors. I was skeptical because most palm s/w isn't more than $100, but this is well worth it.
