I think that I posted an Applescript that added all tasks that had a time other that 00:00 to iCal - on the assumption that they were worth being in your calendar.

[QUOTE=whpalmer4;55945]Just how much "hard landscape" stuff do you want to have in your calendar? And why would you want to have everything that you had flagged be synced into the calendar? That would seem to guarantee that you end up with a lot of stuff that is not "hard landscape" in the calendar![/QUOTE]

I'm using flags to mark two things: First, all the items that I intend to finish today regardless of their actual due date, and second, all the things that I need to keep on my mind that particular day.

This items are (besides appointments) what makes my hard landscape of the day.

Usually I have some 15 items at the beginning of the day.

Why sync to iCal? Because...
 

I'm a dinosaur who doesn't use a cell phone. I do use an older Sony Clie Palm handheld. Syncing OF to iCal means I can then sync to my Palm the items I'll need when I'm not at my laptop.
Syncing with iCal was one of the features I needed when I chose OF.
