This may be slightly off-topic, but why don't synced tasks with due dates have alarms turned on by default? (AFAIK, you have to turn them on manually in iCal.) I would prefer that synced tasks be calendar events, but I could handle them being to-do items if the alarms were turned on automatically. (For me the point in syncing with iCal is visibility - I look at my calendar, and I don't look at the To-Do items, so I would prefer that tasks show up as all-day events. But if I had an alarm that popped up in my face, I could deal with them not being on the calendar.)
