I love this latest 9.0.1.2 version. It has added many features that I love from AsterWare's Sudoku for Palm (I have a Tungsten E2 before I bought my Samsung Galaxy S 4G Andriod). The Palm is not networked.
But, I would like to recommend a feature: Enter a puzzle. For example, you want to solve a puzzle from today's newspaper (you remember those things you used to line your birdcage with).
I know there's a big difference in that AsterWare Sudoku for Palm is not designed to be networked. Another feature it has is that it can generate puzzles. And it has a lot more hints. But, all these features go away from the entire competition network idea.
