Oh, guess I've used a beta version a while ago, then. Actually, I found it had some bugs back then, but I also found that I didn't really have a need for it, anyway - thus I uninstalled it.
I think weather information, for example, should be integrated into other applications. Perfect for me would be: A menubar icon showing the current weather and temperature (I know, exists already...) and the forecasts could be implemented in iCal. There I could have week view and it'd show me my appointments as well as icons of what the weather's going to be like. That'd be nice. (Agendus 9 and up for PalmOS does that quite nicely...)
