With the huge vote for a native IOS / iPad app, I'm hoping that the PB folks are seriously considering this. Without seeing any direct response on the topic, I'm not getting any hopes up but hoping they do comment at some point one way or another. I understand the strategy on the WebBrain, but there are two issues with that in my scenario (aside from the additional monthly fee):
1. Any work related info I have is not allowed to be stored on external systems.
2. Even for other things, using graphical a web app like this is more painful vs. the more instantaneous response (and potentially better capabilities) of a native app.
So a native app with direct sync capability would definitely a much better experience on the iPad.
