Right now, I keep iCal and Address Book synchronized with both my Palm and the Palm Desktop application. To do this I have to employ a pretty cumbersome workflow. I first synchronize via iSync. Then I open the HotSync Manager to change the Conduit Settings. With the defaults for the Address Book, Date Book, and To Do Lists conduits set to "Do Nothing" I change them to "Synchronize", without making that the default.
The next time I perform a HotSync it will then synchronize items with the Palm Desktop application, instead of iCal and Address Book. This means however that I will have to always hotsync twice, if I want to keep everything in sync. Not only that, I have to manually change those conduit settings every time.
I do understand that iCal and Address book are meant to supplant the Desktop application. However, there are some features that I would very much miss, if I had to give it up completely:
1) Linking of records; while it doesn't show up on the Palm, I can link for example husbands and wifes with each other or an appointment to the address book entry of the person I meet with.
2) I like the integratedness of the Palm Desktop application. I still have to use it anyway, if I want to access my notes.
